Answer:
1) Centrifugal separation is another technique commonly used to separate fat from milk to make skim milk. As suggested by the name, centrifugal separation relies on the use of a centrifuge, which spins containers of milk at forces as high as 5,000 to 10,000 times that of gravity.

2)Winnowing is a process of separating grains from husks. In this process, the mixture of grain and husk is dropped from a height. The heavier grain particles fall down straight to the ground while the lighter husk particles are taken away by wind and are collected separately at a small distance from the pile of grains.
3)Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
5)When the solution equilibrium point is reached and no more solute will dissolve, the solution is said to be saturated. A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved.
6)The solid which collects in the filter paper is called the residue. The clear liquid which passes through the filter paper is called the filtrate.
7)Solution: Sieving is a method in which fine particles are sieved through holes of the sieve while the bigger impurities remain on the sieve. Sieving is used in a flour mill to separate impurities like husk and stones from wheat before grinding it.
8)This is the methodology use to practice at home for cleaning bigger impurities dirt, stones, small pebbles from foodgrains which is visible from naked eyes. This is another method by which food grains can be clean by sepration of lighter components by blowing air.
