Question. How will you separate husk or dirt particles from a given sample of pulses before cooking?
Answer: Husk and dirt particles are separated from pulses by hand picking.
Question. How would you obtain clear water from a sample of muddy water?
Answer: By Sedimentation and decantation: Allow muddy water to stand. Mud gets settled down in the water. Slowly pour water to another container. We can also obtain pure water from muddy water by filtration.
Question. How will you separate sand and water from their mixture?

Question. Why do we need to separate different components of a mixture? Give two examples.
Answer: We need to separate different components of a mixture:
(i) To separate harmful or non-useful substances that may be mixed with it.
(ii) To separate even useful components if we need to use them separately.
Examples: (i) Milk or curd is churned to separate the butter.

Question. What is sieving? Where is it used?
Answer: Sieving is a method of separation which allows the fine flour particles to pass through the holes of the sieve while the bigger impurities remain on the sieve. It is used at home to separate pebbles and stones from sand.
Question. What is winnowing? Where is it used?
Answer: Method of separating the components from a mixture is known as winnowing. In this method heavier and lighter components of a mixture are separated by wind or by blowing air. This method is used to separate grains from husk.
Question. Lemonade is prepared by mixing lemon juice and sugar in water. You wish to add ice to cool it. Should you add ice to the lemonade before or after dissolving sugar? In which case would it be possible to dissolve more sugar?
Answer: We should add ice after dissolving sugar because the dissolving power of water decreases with decrease in temperature. So, if we add ice before dissolving sugar, less amount of sugar will get dissolved.
