Class 6 Science Chapter 5 Exercise Question Answer Page N0. 44

1. Why do we need to separate different components of a mixture? Give two examples.

Ans: We need to separate different substances present in a mixture due to the following reasons :

1. To remove the unuseful or harmful components.
2. To obtain the useful components.
3. To remove impurities for getting a pure sample.

Eg.

1. Tea leaves are separated from liquid with a strainer while preparing tea.
2. Grain is separated from stalks, while harvesting.

2. What is winnowing? Where is it used?

Ans :

1. Winnowing is used to separate heavier and lighter components of a mixture by wind or
   by blowing air.
2. This method is commonly used by farmers to separate lighter husk particles from
   heavier seeds of grain.

3. How will you separate husk or dirt particles from a given sample of pulses before cooking?

Ans: The husk particles or dust particles are separated from pulses by the method of handpicking. The unwanted particles are present in small quantities in the total amount of pulses. So they are separated by handpicking before cooking the pulses.

4. What is sieving? Where is it used?

Ans:

1. Sieving allows fine particles to pass through the holes of the sieve, while the bigger
   particles like pieces of dust, stone, husk, etc., remain on the sieve.
2. In a flour mill, impurities are removed from wheat by sieving.

5. How will you separate sand and water from a mixture?

Ans:

A mixture of sand and water can be separated by the sedimentation and decantation methods. Take a glass tumbler half-filled with the given sample of water and stir the water thoroughly. Now keep the tumbler undisturbed for some time. We must see that sand is settled down at the bottom of the tumbler. This process is sedimentation. Now pour the clear water into another tumbler, without disturbing the layer of sand. This process is decantation.

In this way, a mixture of sand and water can be separated.

6. Is it possible to separate sugar mixed with wheat flour? If yes, how will you do it?

Ans: Yes, it is possible to separate sugar mixed with wheat flour. The mixture of sugar and wheat flour can be separated by sieving. The wheat fine particles are separated by the sieve and sugar particles being bigger in size remain on the sieve. Thus, sugar can be separated from the mixture of sugar and wheat flour.

7. How would you obtain clear water from a sample of muddy water?
Ans:

1. Muddy water is allowed to stand in a beaker.
2. Mud settles at the bottom. It is called sedimentation.
3. It is poured into another beaker. It is decantation.
4. This water is filtered again to remove small traces of mud particles.

8. Fill up the blanks

Ans :

a) The method of separating seeds of paddy from its stalks is called ___________.

b) When milk, cooled after boiling, is poured onto a piece of cloth the cream (malai) is left behind on it. This process of separating cream from milk is an example of ___________.

c) Salt is obtained from seawater by the process of ___________.

d) Impurities settled at the bottom when muddy water was kept overnight in a bucket. The clear water was then poured off from the top. The process of separation used in this example is called ___________.

Ans :

1. Threshing
2. Filtration
3. Evaporation
4. Sedimentation and decantation.

9. True or false?

1. A mixture of milk and water can be separated by filtration.
2. A mixture of powdered salt and sugar can be separated by the process of winnowing.
3. Separation of sugar from tea can be done with filtration.
4. Grain and husk can be separated with the process of decantation.

Ans :

1. False
2. False
3. False
4. False

2. It will be possible to dissolve more sugar before adding ice.
3. Because more sugar can be dissolved in a hot solution than in a cool solution.

Note :- Solubility of a solid in liquid increases with an increase in temperature.
