Physical and Chemical Changes Class 7 Extra Questions Long Answer Type

Question 1.
Why is the burning of a candle considered a chemical change?
Answer:
Candles are made of wax and a long thread of cotton (called wick of the candle). While candle is burnt, the molten wax goes up through the thread and undergoes combustion to form carbon dioxide and water vapour. The ‘wick’ of the candle gets changed to a black mass.

Over the process, heat and light energy is given out. It is not possible to
(i) recover the burnt wax again,
(ii) recover the thread again.
Hence, the burning of a candle is a chemical change.

Question 2.
State the differences between chemical and physical changes.
Answer:

Chemical changePhysical change
(i) It is generally a irreversible process.(i) It is generally a reversible process.
(ii) A new substance is formed.(ii) No new substance is formed.
(iii) Properties of a substance changes.(iii) Properties of a substance does not changes.
(iv) Energy is given out or absorbed during the change.(iv) No energy is given out or absorbed during the change.

Question 3.
What happens when iron nails are dipped in copper sulphate solution?
Answer:
When iron nails are dipped in copper sulphate solution, a brown layer of copper gets deposited on the surface of iron nails after some time. This happens due to the reaction between copper sulphate and iron. Also, the colour of copper sulphate changes from blue to green due to the formation of iron sulphate.
Physical and Chemical Changes Class 7 Extra Questions and Answers Science Chapter 6 3

Question 4.
Most of the physical changes are reversible but some are irreversible. Explain the statement with examples.
Answer:
In physical change, a substance undergoes a change in its physical properties only. Physical change occurs when there is a force applied, change in temperature, etc., on a substance. Most of the physical changes are reversible like rolling a dough into a chapati and then again bringing back into a dough.

Making a toy aeroplane by folding the paper and then again unfolding the toy aeroplane to recover the page. But when a physical change cannot be reversed or we cannot bring the substance back to its original shape, size, state, etc., is known as irreversible change. For example, baking chapati or making a toy aeroplane by cutting the paper instead of folding it.

I do not support unfair means in the examination because it degrades the standard of education.

You are Ashok living at 7, Mall Road, Shimla. Write a letter to your friend Sushil to give an advice for taking part in games. Answer:
7, Mall Road
Shimla
14th July, 20XX

Dear Sushil
Our friend Sharda tells me that you do not take part in games. You are a book – worm. You always indulged in books. Even in the evening you never stir out of your room. You never go to the play – field. You do not take interest in any game. You do not care to see the important hockey and football matches that are played in the local field. This is really very lamentable. Only books cannot make your life happy. So games are as important as books in life. Games teach us teamship, discipline and endurance. They makes us strong, healthy and active. I would, therefore, advise you to shake off your laziness and take part in outdoor games.

Your friend
Ashok.

Dear Brother
What a nice present you sent me! Five thousand rupees! Thank you very much for the gift. A big amount like five thousand rupees means a great deal to me. I long wished to buy a radio–set. But I could not get it due to lack of money. Running commentaries on cricket being played attracted me most. I shall be able to spend my time in a better way now. A radio – set of my choice may cost about Rs. 400/–. I should like to have some books. But what I want most is a table – watch. Now my examination is fast drawing near. Sometimes I need to get up very early. The table – watch may cost about Rs. 800/–, I like many other things. But these are the things I like most. I hope you are in the best of health.

Acids, Bases and Salts Class 7 Extra Questions Long Answer Type

Question 1.
Explain the process of neutralisation with the help of an activity.
Answer:
When an acidic solution is mixed with a basic solution, both the solutions neutralise the effect of each other. The resulting solution is neither acidic nor basic. We can show the process of neutralisation with the help of an activity.

Fill one-fourth of a test tube with dilute hydrochloric acid. Note down its colour and also the colour of . phenolphthalein solution. Add 2-3 drops of the indicator to the acid. Shake the test tube gently. We observe that solution remains colourless. Add sodium hydroxide solution in the test tube drop by drop with continuous stirring till the pink colour just appears. Appearance of pink colour indicates that the neutralisation reaction has completed.

Question 2.
What are the applications of neutralisation reaction in everyday life?
Answer:
Neutralisation helps us in many ways in our everyday life. Some of the applications are:

  1. Indigestion: When we suffer from acidity we take antacid to get relief. Antacid neutralises the effect of excessive acid.
  2. Ant bite: When an ant bites, moist baking soda solution or calamine solution is rubbed which neutralises the effect of acid injected into the skin when an ant bites.
  3. Soil treatment: Plants do not grow well when the soil is too acidic or too basic. When the soil is too acidic, it is treated with bases like quick lime or slaked lime and when it is basic, organic matter is added to it. Organic matter releases acids which neutralise the basic nature of the soil.
  4. Factory wastes: The factory wastes contain acids, they are harmful for water bodies. To neutralise these wastes, basic substances are added to them.

Question 3.
Shweta took a little sodium hydroxide in a beaker and dipped a red litmus paper into it. She observed red litmus paper turned blue.
She took dilute hydrochloric acid in the same beaker and dipped a blue litmus paper into it. The blue litmus paper did not turn red. Why?
Answer:
Shweta took dilute hydrochloric acid in the same beaker containing sodium hydroxide solution. Mixing of base into acid forms salt which is neutral and does not change colour of either blue or red litmus paper.

Question 4.
Why litmus is better natural indicator than other natural indicator?
Answer:
Litmus give wide range of colour change from weak acid to strong acid and from weak base to strong base. Other natural indicator, on the other hand, do not show a wide colour change.
