b) Peanuts and peas
c) Water and flour
d) Salt and kidney beans
e) Powdered sugar and grains
f) Red and yellow beads

Accepted Answer

a) Sand and sawdust can be separated by the method of winnowing. In this heavier sand particles and lighter sawdust particles are separated by blowing wind or air.

b) Peanuts and peas are the components that are larger in size, they can be separated by hand picking method.

c) Water and flour can be separated using sedimentation and decantation. Flour is of fine particles and is insoluble in water. If the mixture is allowed to stand for some time, the flour would settle at the bottom, after which the water can be decanted to another vessel slowly, without disturbing the sediment.

d) Salt and kidney beans can be separated by sieving, using a sieve with holes that are bigger than that of salt but smaller than kidney beans.

e) Powdered sugar and grains can be separated by filtration and then sun-dried to get clean grains. The drained off water can be evaporated to obtain the small amount of sugar that was washed off.

f) A mixture containing red and yellow beads can be separated by handpicking.
