II.LONG ANSWER TYPE QUESTIONS

1. Why did Jumman Shaikh and Algu Chowdhry, the two good friends, become sworn enemies?
Ans: Jumman and Algu were fast friends. They trusted each other blindly. But an incident broke them apart. Jumman had got the property of his old aunt. But after some duration he began to ignore and ill treat her. She demanded a monthly allowance or the return of her land. The panchayat was called to hear the case. Algu as the head Panch decided the case in favour of the old aunt. The two friends became sworn enemies.

2. How did Jumman and Algu get over their bitterness and become friends again?
Ans: Jumman Shaikh and Algu Chowdhry broke up when Algu gave his verdict in favour of Jumman’s aunt. Algu heard the voice of his conscience and did justice. But Jumman waited for his turn to take revenge. He got that chance soon. Algu was being cheated by Sahu. Hence, a panchayat was held. Sahu named Jumman as head Panch. But as soon as Jumman occupied that seat of responsibility, he too decided the case on facts and merit. His verdict in favour of Algu brought them closer once again.

3.Which is more desirable-friendship or enmity? When does a person hear strongly the voice of his conscience?
Ans: It goes without saying that friendship is based on goodwill and respect for one another. Enmity is created by hatred and ill-will. Friendship is definitely far better than enmity. Every person has a weakness for friends. But the moment he occupies the seat of judgement, he hears the voice of his conscience and gives a fair verdict.

NCERT Solutions for Class 6 Science Chapter 5 Separation of Substances LAQ Q1

2. Describe the method to obtain salt from sea water.
Ans. Sea water contains many salts mixed in it. One of them is common salt, when sea water is allowed to stand in shallow pits, water gets evaporated by sunlight and slowly turns into water vapour. In a few days, the water evaporates completely leaving behind the solid salts. Common salt is then obtained from this mixture of salts by further purification.

3. What is decantation?
Ans. Decantation is a process, of separation of insoluble solids from liquid. The suspension of solid particles in liquid is allowed to stand for some time. The solid particles then settle down at the bottom of the container and clean water goes up. Without disturbing the settled particles the clean water is transferred into other container.

 4. Where is decantation used? Give two examples.
Ans.
(i) Decantation is used to separate insoluble solids or liquid from liquid. Rain water is a mixture of mud and water. It is purified by decantation.
(ii) Oil and water also get separated by this method because oil floats up.

 5. How will you prepare cheese (paneer)?  
Ans. For making paneer, a few drops of lemon juice sire added to milk as it boils. This gives a mixture of particles of solid paneer and liquid. The paneer is then separated by filtering the mixture through a fine cloth or strainer.

6. Explain the method that can be used for separating the following mixture:
(i) Sand and husk
(ii) Wheat, sugar and stalk
(iii) Water and petrol
(iv) Rice and salt
(v) Sand and salt
Ans.
(i) Mixture of sand and husk: Sand and husk can be separated by the method of winnowing.
(ii) Mixture of wheat, sugar and stalk: For separating stalk from the mixture we should follow the winnowing method because milk is lighter than other two components and get separated. Wheat and sugar can be separated by sieving because they are in different sizes.
(iii) Mixture of water and petrol: Water does not dissolve in petrol. So, it can be separated by the use of separating funnel.
(iv) Mixture of rice and salt: Rice and salt can be separated by sieving.
(v) Mixture of sand and salt: Sand and salt is mixed with water, salt dissolves in water and sand can be separated solution by sedimentation and decantation followed by filtration. After that using evaporation common salt is separated.
