Centrifugation can be used for:
Centrifugation can be used for:
The correct options are
A Separation of cream from milk
B Drying of wet clothes in washing machine
C Separation of blood components in medical science
Centrifugation is a method used for separating solids from liquids, where the mixture is homogenous.
Centrifugation can be used for:
(a) Separation of cream from milk. The milk is rotated into the centrifuge. At very high speed. In this way, the denser particles settle at the bottom and the lighter ones float over the surface and cream is lighter than milk will float on the top and can be easily extracted out of the milk and can be separated easily.
(b) Drying of wet clothes in a washing machine. This is because in centrifugation the solution or wet clothes are simply spun very fast and because of this the water comes out very easily and then the clothes are dried.
(c) Separation of blood components in medical science. The technique to separate white blood cells from red blood cells is a centrifuge, which involves spinning. Blood is separated in a centrifuge rather than settling by itself because the heavier parts of the mixture wouldn't be pushed too the edge.
But, to obtain salt from sea water, evaporation or crystallisation is used.
