WRITING
“If you work hard and know where you’re going, you’ll get there,” says Evelyn Glennie. You have now read about two musicians, Evelyn Glennie and Ustad Bismillah Khan. Do you think that they both worked hard? Where did they want to ‘go’?
Answer these questions in two paragraphs, one on each of the two musicians.

Answers
Yes, I think they worked really very hard in their lives. Evelyn became deaf in her early age. This could be a great physical handicap. But she didn’t feel disheartened. She worked like a workaholic. She achieved worldwide recognition. She herself admitted that she had to work often harder than a classical musician. While as a young girl, Evelyn noticed a girl playing a xylophone. She decided there and then that she wanted to play it too. Soon she realized her wish. Through hard work she captured most of the top awards.

Bismillah Khan too worked very hard. He used to sit practising throughout the day. He would sit at the banks of the Ganga and practise in solitude. He felt inspired from the Ganga to invent new ragas. Bismillah Khan’s hard work brought him the country’s highest civilian award the ‘Bharat Ratna’. This is the maximum that an artist can go to.

NCERT Solutions for Class 12 History Chapter 1 Bricks, Beads and Bones The Harappan Civilisation

Question 1.
List the items of food available to people in Harappan cities. Identify the groups who would have provided these.
Solution :
(a) The following items of food were available to people in Harappan cities : Wheat, barley, lentil, chickpea, sesame, millets, rice, fish, and goat.
(b)

  • Animals such as cattle, sheep, buffalo and pig were domesticated. So, they could get meat from these animals.
  • The evidence of a ploughed field at Kalibangan and knowledge of bull prove that harvesting was done by the Harappans.
  • Regarding hunting of wild animals such as boar, deer and gharial, there is no proof whether the Harappans hunted these animals themselves or obtained meat from other hunting communities.

Question 2.
How do archaeologists trace socio-economic differences in Harappan society? What are the differences that they notice?
Solution:
Following examples can be cited to show the existence of social and economic variations : in the Harappan society:
(i) Study of burials is one example. In the Harappan sites, the deads were usually laid in pits. There were differences in the Way burial pits were made. At some instances, the hollowed-out spaces were lined with bricks. But these may not be taken as an indication of social differences.
(ii) In some graves pottery and ornaments have been found. Jewellery has been found from the graves of men and women as well. These findings can point out social and economic differences. ‘
(iii) The artefacts have been classified into two categories, Utilitarian and Luxurious. Objects of daily uses and objects made of ordinary materials made of clay or stone come under utilitarian category. Ordinary articles consisted of querns, pottery, flesh-rubbers and needles. These have been found distributed throughout settlements.
(iv) Objects of luxuries were rare and made from precious, non-local materials. The technology used was advanced and complicated. Little pots of faience were considered precious. They were also not easy to make. These show the existence of social and economic variations in the Harappan society.

Question 3.
Would you agree that the drainage system in Harappan cities indicates town planning? Give reasons for your answer.
Solution :
The drainage system in Harappan cities indicates town planning as is clear from the following reasons :

  • It was planned drainage system. In the Lower Town, the roads and streets were laid out along an approximate “grid” pattern, intersecting at right angles.
  • It seems from the plan of the Lower Town that streets with drains were laid out first and then houses built along them.
  • The drains of every house were connected to the street drains. Very long drainage channels were provided at intervals with sumps for cleaning. Drainage system has been found in smaller settlements like Lothal.

Question 4.
List the materials used to make beads in the Harappan civilisation. Describe the process by which any one kind of bead was made.
Solution :
(a) The materials used to make beads in the Harappan civilisation were as given below:

  • Stones like carnelian of a beautiful red colour, jasper, crystal, quartz, and steatite;
  • Metals like copper, bronze, and gold;
  • Shell, faience, and terracotta or burnt clay.

(b)

  • The process or technique for making beads differed according to the material.
    For example, steatite, a very soft stone, was easily worked. Some beads were moulded out of a paste made with steatite powder. This permitted making a variety of shapes, unlike the geometrical form that were made out of harder stones.
  • Red colour of carnelian was obtained by firing the yellowish raw material and beads at various stages of production.
  • Nodules were chipped into rough shapes, and then finely flaked into the final form.
  • Grinding, polishing, and drilling completed the process.

Question 5.
Look at figure and describe what you see. How is the body placed? What are the objects placed near it? Are there any artefacts on the body? Do these indicate the sex of the skeleton?
Solution :
(a) A dead body has been laid in a pit.
(b) Some objects of pottery are placed near it.
(c) There seems to be some ornaments on body but these do not indicate the sex of the skeleton because jewellery has been found in burials of both men and women.

Question 6.
Describe some of the distinctive features of Mohenj odaro.

Or

Describe the features that justify that Mohenjodaro was a planned urban cetnre.
Solution :
Some of the distinctive features of Mohenjodaro were as given below :

  1. Mohenjodaro is the most well known site. It was divided into two sections – one smaller but higher and the other much larger but lower. These are known as the Citadel and the Lower Town, respectively. Both the sections were walled.
  2. Several buildings were built on platforms which implies that the building activity was restricted on the platforms. It seems that the settlement was first planned and then implemented accordingly.
  3. The standardised ratio of bricks – sundried or baked – is also a sign of planning. The length and breadth of bricks were four times and twice the height, respectively.
  4. There was well-planned drainage system. The roads and streets were laid out along an approximate “grid” pattern, intersecting at right angles. It appears that streets with drains were laid down first and then houses built along them.
  5. Residential buildings were centered on a courtyard, with rooms on all sides. There were no windows in the walls along the ground level to have privacy. The main entrance too did not give a direct view of the courtyard.
  6. There was a bathroom in everyhouse. The drains were connected to the street drains.
  7. Some houses had staircases to reach a second story or the roof.

Question 7.
List the raw materials required for craft production in the Harappan civilisation and discuss how these might have been obtained.
Solution :

Following is the list of materials required for craft production in the Harappan Civilisation:
Stone, clay, copper, tin, bronze, gold, faience, shell, camelian, jasper, crystal, steatite, quartz, timber.
Some of the raw materials were locally available whereas some were purchased from the distant places. Soil and wood were locally available raw materials. Stones, fine quality wood, metals were procured from distant places.
Settlements of the Harappans were situated at such places where raw materials were easily available. Nageshwar and Balacot were famous for shell. Some places were famous for Lapis Lazuli like Shortughai in Afghanistan. Rajasthan and Gujarat were famous for copper. Lothal was famous for camelian.

Another way of obtaining raw material was sending expeditions to different places.
Evidences show that expedition was sent to Khetri region of Rajasthan for copper and to South India for Gold. Through these expeditions local communities were contacted. Harappan evidences found at these places indicate contacts between each other. Evidences found at Khetri region were given the name of Ganeshwar Jodhpura Culture by archaeologists. Huge reserves of copper products were found here. It is assumed that inhabitants of these area sent copper to Harappan people.

Question 8.
Discuss how archaeologists reconstruct the past.
Solution :
It is the material evidence by which the archaeologists reconstruct the past. This material could be pottery, tools, ornaments and household objects. It is done in the following ways:

  1. Classifying finds : The archaeologists classify their finds in terms of material, such as stone, clay, metal, bone, ivory, etc. and in terms of function i.e., an artefact is a tool or an ornament or both or something meant for ritual use.
  2. The archaeologists try to reconstruct religious practices because certain objects which seemed unusual or unfamiliar may have had a religious significance. For example, terracotta figurines of women, heavily jewelled, some with elaborate head dresses were regarded as mother goddesses.
  3. Religious beliefs and practices are reconstructed by examining seals, depicting ritual scenes, animals (one, horned animal) cross-legged yogic figure.
  4. Many reconstructions are made on the assumption that later traditions provide parallels with earlier ones because archaeologists move from present to the past. The example is ‘proto-Shiva’ seal which can be compared with Rudra mentioned in Rigveda.

Question 9.
Discuss the functions that may have been performed by rulers in Harappan society.
Solution :
The functions that may have been performed by rulers in Harappan society whereas mentioned below –

  1. There are indications of complex decisions being taken and implemented in Harappan society. For example, the extraordinary uniformity of Harappan artefacts as evident in seals, pottery, weights and bricks would have due the authority of the rulers. A large building has been found in Mohenjodaro. It might be a palace for the rulers. A stone statute has been labelled as ‘priest-king’. Thus, he may be a ruler who exercised authority for taking various decisions.
  2. Whether the ritual practices were performed by the ‘priest-king’ is not clear because these practices of Harappan civilisation are not well understood yet nor are there any means of knowing whether those who performed them also held political power.

Question 10.
What role does the molecular interaction play in a solution of alcohol and water?
Answer:
Alcohols dissolve in water due to the formation of intermolecular H-bonding with water.

Question 11.
Why do gases nearly always tend to be less soluble in liquids as the temperature is raised?
Answer:
The dissolution of a gas in a liquid is exothermic in nature because the gas contracts in volume.

Gas + Liquid ⇌ Dissolved gas ; ∆H = – ve

An increase in temperature will favour the reverse process since it is of endothermic nature. Therefore, the solubility of the gas in the solution decreases with the rise in temperature.

Question 12.
State Henry’s law and mention some important applications.
Answer:
Henry’s law: According to this law, ‘The mass of a gas dissolved per unit volume of a solvent at a constant temperature, is proportional to the pressure of the gas with which the solvent is in equilibrium’.

Let in unit volume of solvent, the mass of the gas dissolved is m and equilibrium pressure is P, then m α P or m = KP, where K is a constant. We can understand Henry’s law by taking the example of soda water bottle. Soda water contains carbon dioxide dissolved in water under pressure.

Applications of Henry’s law:

1. In the production of carbonated beverages: To increase the solubility of CO2 in soft drinks, soda water, bear etc. the bottles are sealed at high pressure.

2. In exchange of gases in the blood: The partial pressure of O2 is high in inhaled air, in lungs it combines with hemoglobin to form oxyhemoglobin. In tissues, the partial pressure of oxygen is comparatively low therefore oxyhemoglobin releases oxygen in order to carry out cellular activities.

3. In deep-sea diving: Deep-sea divers depend upon compressed air for breathing at high pressure underwater. The compressed air contains N2 in addition to O2, which are not very soluble in blood at normal pressure. However, at great depths when the diver breathes in compressed air from the supply tank, more N2 dissolved in the blood and in other body fluids because the pressure at that depth is far greater than the surface atmospheric pressure. When the divers come towards the surface at atmospheric pressure, this dissolves nitrogen bubbles out of the blood. These bubbles restrict blood flow, affect the transmission of nerve impulses. This causes a disease called bends or decompression sickness. To avoid bends, as well as toxic effects of high concentration of nitrogen in the blood, the tanks used by scuba divers are filled with air diluted with helium (11.7% He, 56.2% N2, and 32.1% O2).

4. At high altitudes: At high altitudes, the partial pressure of O2 is less than that at the ground level. This results in a low concentration of oxygen in the blood and tissues of the people living at high altitudes or climbers. The low blood oxygen causes climbers to become weak and unable to think clearly known as anoxia.

5. Aquatic life: The dissolution of oxygen (from air) in water helps in the existence of aquatic life in various water bodies like Lake, rivers, and sea.

Question 13.
The partial pressure over a saturated solution containing 6·56 x 10-2 g of ethane is 1 bar. If the solution contains 5·0 x 10-2 g of ethane, what shall be the partial pressure of the gas?
Answer:
According to Henry’s law,
The mass of the gas (m) dissolved in solution ∝ Partial pressure (p) (At constant temperature)

Question 14.
What is meant by positive and negative deviations from Raoult’s law and how is the sign of ∆Hsol related to positive and negative deviations from Raoult’s law?
Answer:
(a) Positive Deviation:
(i) ∆Vmixing is positive: This is quite likely also because in ge presence of weak forces of interaction, interaction, the volume of the solution is bound to increase.
(ii) ∆Hmixing is positive: Energy is needed to form the solution because the components of the solution have to be brought closer to form the solution. Thus, the process of mixing is of endothermic nature.
NCERT Solutions for Class 12 Chemistry Chapter 2 Solutions 33
(b) Negative Deviation:

(i) ∆Vmixing is negative: Because of the increased forces of interaction, the molecules of the two components will come closer and as a result, there is a decrease in the volume of the solution.
(ii) ∆Hmixing is negative: Energy is expected to be released because of the increase in the forces of interaction. Therefore, the process of mixing is exothermic in nature or ∆Hmixing is negative.

Question 23.
Suggest the most important type of intermolecular attractive interactions in the following pairs :

  1. n-hexane and n-octane
  2. I2 and CCl4
  3. NaClO4 and water (H2O)
  4. methanol and acetone
  5. acetonitrile (CH3CN) and acetone (C3H6O).

Answer:

  1. Both are non-polar. Hence, intermolecular interactions in them will be London/ dispersion forces (discussed in class XI)
  2. Both are non-polar. Hence, intermolecular interactions in them will be London/ dispersion forces (discussed in class XI)
  3. NaClO4 gives Na+ and ClO4 ions in the solution while water is a polar molecule. Hence, intermolecular interactions in them will be ion-dipole interactions.
  4. Both are polar molecules. Hence intermolecular interactions in them will be dipole-dipole interactions.
  5. Both are polar molecules. Hence intermolecular interactions in them will be dipole-dipole interactions.

Question 24.
Based on solute-solvent interactions, arrange the following in order of increasing solubility in n-octane and explain.
Cyclohexane, KCl, CH3OH, CH3CN.
Answer:
(i) Cyclohexane and n-octane both are non-polar. Hence they mix completely in all proportions.
(ii) KCl is an ionic compound while n-octane is nonpolar. Hence, KCl will not dissolve at all in n-octane.
(iii) CH3OH and CH3CN both are polar but CH3CN is less polar than CH3OH. As the solvent is non-polar, CH3CN will dissolve more than CH3OH is n-octane.
Thus the order of solubility will be KCl< CH3OH < CH3CN < Cyclohexane.

Question 25.
Among the following compounds, identify which are insoluble, partially soluble, and highly soluble in water?
(i) phenol
(ii) toluene
(iii) formic acid
(iv) ethylene glycol
(v) chloroform
(vi) pentanol.
Answer:
(i) phenol (C6H5OH): Is partially soluble in water due to weak dipole-dipole interactions in the molecules of phenol and water.
(ii) toluene (C7H8): Is insoluble in water because it is an aromatic hydrocarbon (non-polar) while water is polar in nature.
(iii) formic acid (HCOOH): Is highly soluble in water since it can form hydrogen bonding with water.
(iv) ethylene glycol (HOCH2CH2OH): Is highly soluble in water since it can form hydrogen bonding with water.
(v) chloroform (CHCl3): Is insoluble in water because it is an organic heavy liquid and forms a separate layer.
(vi) pentanol (C5H11OH): In partially soluble in water because the bulky C5H11 group decreases its extent of hydrogen bonding with water.

Question 26.

Question 31.
The depression in freezing point of water observed for the same amount of acetic acid, trichloroactetic acid and trifluoroacetic acid increases in the order given above. Explain. (C.B.S.E. 2008 Supp.)
Answer:
The depression in freezing point of a solute in water depends upon the number of particles or ions furnished by it in solution or upon its degree of dissociation (α). All the three organic acids ionise in aqueous solution. However, the relative order of acidic strengths is as given below.
NCERT Solutions for Class 12 Chemistry Chapter 2 Solutions 53

This is linked with the electronegativity of the halogen atoms present. Fluorine (F) is more electronegative than (Cl). Under the circumstances, trifluoroacetic acid gives maximum ions in solution since it is the strongest acid. Consequently, the depression in freezing point (∆Tf) is the maximum in this case and is the least for acetic acid which is the weakest acid.

1. Yes, I remember a memorable holiday, I spent with my grandmother last month. Our school was closed for autumn break. I directly went to my grandmother who lives in a village. When she saw me she burst out like a beautiful flower. She hugged me. Then she offered me certain delicacies like home-made halwa, puree and kheer. She took me to the temple in the evening.

She asked me to pray to the goddess for prosperity of all. During evening she narrated the stories of our scriptures, The Ramayana, The Mahabharata, and The Panchtantra. She advised me that man’s good deeds always remain with him and these make him great. Doing good deeds and helping the needy ensures contentment. She told me that God loves those who love their fellow-beings. I had never heard such things earlier. These had an indelible impression on me. I promised her to follow her advice in my life and actions.

2. Like all grandmothers my mother also told me a story. It was of two cats and a monkey. The two cats got a chapati from somewhere. They started fighting over the chapati. Both of them wanted more of it. But they couldn’t understand how this could be divided equally between the two. They decided to take external help to settle the issue. By chance a monkey came their way. They told the monkey about their problem. The monkey asked them to wait for a few minutes. He reappeared with a balance and asked the cats to give the chapati to him. He knowingly made two pieces of it- one bigger and the other smaller.

He then put these two pieces on both the sides of the balance. When he balanced them to weigh one side went upwards and the other remained low. He tore a major part of the piece of chapati from the piece which hung low and ate it up. This side got less weighty and when he balanced, it went up. He then took a major part of the other piece of the chapati. He did this two, three times. By that time the whole chapati stood eaten by him. This amazed the cats as there was nothing left of the chapati for them. They learnt a bitter lesson that they wouldn’t fight. Also they won’t believe in a clever and crafty external force.

3. There are many things I admire the most about my grandmother. These are : her simple and straightforward nature; her simple living; her regular working schedule ; her religious mind and regularity of daily life. It is like rising in the morning, taking a bath, praying and some light physical exercises etc. My grandmother is still agile and active. She does the domestic chores by herself. She takes very simple food and eats those things that are not harmful for health. She never takes fried food.

She never takes cold drinks and never eats street food. Then she helps the needy. She gives charities and attends sermons by the holy men. She has a great faith in holy scriptures. She recites holy prayers by herself while worshipping in her own temple. Thus my grandmother leads a pious, regular and disciplined life. Due to the qualities of head and heart, she is admired and respected by all.

4. Yes, there is much difference between my mother and my grandmother. It is not of temperament or disposition. But it is mainly of physical compulsions of life. My mother has most of the qualities of my grandmother. But she can’t exercise them due to her being in service. She is always short of time and is always in a hurry. However, she has a frugal mind and is very conscious of spending money.

She doesn’t give much in charities as she thinks that giving alms makes the beggars parasites. She can’t pray as she has to leave for her school in the early morning. Then she can’t narrate us stories like our grandmother does. She doesn’t believe in giving a long » rope to the children as she believes that this can spoil them. But my grandmother believes firmly in love and affection. She feels and says that these, together with moral values, can bring wonderful results.

Question 2.
Have you ever been on a trip to any place in India, where you didn’t know the language spoken locally ? How did you feel ? How did you manage to communicate ?
Answer
Yes, I went to Tamil Nadu last year. There I had to face a lot of problems due to the Tamil language. I didn’t know Tamil and they didn’t know Hindi or English. Where I got some educated men to talk to, the problem didn’t arise as I could speak English. But in the rural side near Chidambaram, I really faced a tough time. I felt completely isolated and aloof.

The rural people tried to understand me and I them but I remained non- communicative. However, I spoke some broken words and gesticulated about the things. For instance, I needed vegetarian food and closing my fingers took them towards my mouth. Then I gave out a cock-like sound indicating, I was vegetarian and didn’t take meat etc. They laughed but understood. Then they willingly helped me by showing me the way to a vegetarian hotel. It was altogether a funny incident.

Deliver a speech in the morning assembly at your school about the Importance of Adult Education and ways to implement it.

Read the following to make your speech effective :
The introduction of a speech is like the nose of an airplane. The nose sets the course and leads the plane off in a specific direction. A good introduction sets the direction of your speech by

  • getting the attention of your audience
  • introducing your topic
  • stating your central idea or purpose
  • briefly identifying the main points
  • making your audience eager to hear what you have to say

Answer
Worthy Principal, teachers and fellow-students
Today I, Pradeep, of class IX, stands before you to deliver a speech on the Importance of Adult Education and ways to implement it.- Well, at the outset, I would say that illiterates are liable to be cheated everywhere. They have to be dependent on others for knowing things around them. They are branded as ‘illiterates’ and treated in a hateful way.

They can’t maintain their accounts and can easily be deceived, cheated and befooled. They are discriminated against. They can’t join the mainstream of social life. Their knowledge about what is happening around them is minimal. So they feel handicapped to take part in matters requiring far-sightedness, wisdom and maturity. The importance of Adult Education is seen in the fact that the illiterates get a sense of fulfilment in being literate. They can take advantages of various schemes of the govt, meant for their social, economic and moral uplift.

You’ll agree with me that we as students can render a yeoman’s service in educating these adult illiterates. We can hold Literacy Camps in villages and tell them the advantages of being literate. Literate women can bring a drastic change in their lives. Being literate they can read material on childcare, health and hygiene, and other areas of human knowledge and activity.

They can progress in all fields of human life and raise themselves up in all spheres. They can learn a lot about latest techniques of farming, need for personal hygiene and importance of cleanliness, hygiene, family planning etc. Being literate they can decide what is good or bad for them. We should, therefore, convince the adult illiterates to join the literacy classes whenever they are held.
Thank you very much.

WRITING TASK

Today I am very happy as …………..
Answer
8th July 20xx, Wednesday 8 pm
Today I am very happy to have been gifted with Triveni’s novel Kashi Yatre. I just fell in love with the grand old lady who is the central figure in this novel and identified myself with her. Actually the serialisation of this novel in the Kannada weekly Karmaveera raised in me the desire of knowing more and more about her. I, too, was once drawn towards a feeling of visiting Kashi and worshipping Lord Vishweshwara as the ultimatepunya. I fully supported this old lady in having given all her saving to the orphan girl. She rightly thought it was more an action of punya than visiting Kashi. I, too, could have done the same thing. This help was more punya. This orphan girl couldn’t marry her lover, whom she loved passionately due to poverty. Thus the old lady as the heroine of the novel proved more appreciative because of her qualities of head and heart.

I shall cherish this novel more because it enabled me to be literate. Actually with this novel more sweet memories are intertwined. These are like how I developed fascination for the heroine and how my own granddaughter became my teacher. The craving to know more about the old lady simply motivated me to be literate. Now I can read any novel. I shall keep this Kashi Yatre as my holy book. May my granddaughter live long ! Grandmother

Question 10.
Here is a story about Swami and his grandmother. After reading the excerpt, change it into a conversation between Swami and his Grandmother.
Answer
Swami : Oh, Granny ! You don’t know what a great fellow Rajam is. He has a large heart and is very wise and far-sighted. For instance, he had some sort of enmity with Mani. But he soon became his friend, even though he has a police dress.
Granny : Is it ? Why should he want a police dress ?
Swami : His father is the Police Superintendent and commands over all policemen here.
Granny : Then his office must be tremendous. Swami, your grandfather was a powerful sub-magistrate. Before him his office even the police force and the fiercest dacoits would tremble.
Swami : This is o.k. Granny. Enough of your stories. Now listen. I want to tell you something about Rajam. Do you know how many marks Rajam gets in arithmetic ?
Granny : Does he get all the marks, child ?
Swami : No silly. He gets ninety marks out of one hundred.
Granny : You too must try and get marks like him. You know, Swami, your grandfather used to frighten the examiners with his answers sometimes. He took one tenth of the time that others took to answer the question. And then answers would be so correct that the teachers would give two hundred marks sometimes.
Swami : Oh, enough, Granny ! You relate unnecessary stories. Please listen about Rajam.
Granny : Alright.
Swami : Now listen. Rajam’s father was camping in a forest with his son. Two tigers came upon them suddenly, one knocking his father from behind. The other began chasing Rajam but he took shelter behind a bush and shot that dead with his gun …. Granny, are you asleep ?
