Answer 1

Answer:

Centrifugation

Explanation:

In centrifugation, the colloid (here milk) is rotated at very high speeds. A centrifugal force acts on the solid which makes it move out of the solution and deposits it on the top. This separates the liquid and solid part. For example, milk into skim milk and cream. This cream is basically butter.

Hope it helped!

Answer 2

Explanation: Centrifugation is the technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
