• C. Used in dairies to separate butter from cream.
• D. Used in washing machines to separate water from wet clothes.

Answer 1

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

The correct options are
B

Used in diagnostic laboratories for the separation of blood cells from blood.

C

Used in dairies to separate butter from cream.

D

Used in washing machines to separate water from wet clothes.

In centrifugation, the denser particles of a mixture are forced to the bottom and the lighter particles stay at the top when spun rapidly. So, it is a technique to separate the components of mixtures, based on the difference in the densities of the particles.

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
