b> Is it possible to separate sugar mixed with wheat flour? If yes, How will you do it?
Sand and water can be separated by the process of sedimentation and decantation.
Sedimentation- Sedimentation is the process in which heavier particles of an insoluble solid settle down in a liquid.
Sand being the heavier particle will settle down in the liquid.
Decantation is the process of pouring out the liquid without disturbing the sediment.
From the mixture of sand and water, water can be poured out without disturbing sand.
Sieving - Sieving is a method in which fine particles are sieved through holes of the sieve while the bigger impurities remain on the sieve.
Sugar particles being larger in size are retained by the sieve whereas wheat flour will pass through it.
