Kiran observed his father separating husk and grains by winnowing method in the field and appreciated how wind flow helped in seperation. On evaporation salt is formed from sea water. Isn’t it? How would you appreciate this process?

Explanation:

Grains and husk can be separated from each other by the method of winnowing, because of difference in their density. Husk is lighter than the grains so when we allow them to fall from a height the grain will fall just below but the husk will fall some distance apart from the grain because of the speed of the wind.

 

Evaporation is used to separate salt from the water of seawater. This is because of the difference in their evaporating temperature. Water gets evaporated on a lower temperature than the salt so the only salt will left behind after the evaporation.
