Answer 2

Centrifugation- Separating the suspended particles of a substance from a liquid in which the mixture is rotated at a high speed in a centrifuge.

The process of centrifugation is used in dairies to separate cream from milk.

Crystallization or crystallisation is the (natural or artificial) process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas

.Distillation is the process of separating components of a mixture based on different boiling points. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from air. Humans have been using distillation since at least 3000 BC in the Indus
