Answer 1

Answer: (B), (C), (D)

The correct options are
B

C

Used in dairies to separate butter from cream.

D

Used in washing machines to separate water from wet clothes.

Centrifugation is a technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, and density. It is the sedimentation of particles under the influence of the centrifugal force and it is used for the separation of two miscible substances(homogeneous mixtures). Centrifugation is used to separate small solid particles from liquids. The denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.

Applications of Centrifugation:-

-Used in diagnostic laboratories for separation of different components in blood.

-Used in dairies to separate butter from cream.

-Used in washing machines to separate water from wet clothes.
