Solution
- In everyday life, we use a number of mixtures and the need for the separation of useful components from the mixture often arises. The separation of substances can be done through various methods like hand-picking, threshing, sieving, winnowing, etc.
- The principle of winnowing is that if the solid-solid mixture contains two substances and one substance is lighter than another, then the lighter substance can be separated from the heavier one by blowing air or wind.
- For example, Chaff is separated from rice using this method.
