Using Temperature in Separating Mixtures

Evaporation or Boiling

This technique is used when a dissolved component needs to be recovered from a solution. It relies on the different substances in a mixture having different boiling points. The mixture can be left out in the open and the component with the lowest boiling point will evaporate, leaving the other substance behind.

Freezing

This technique can be used to separate two liquids when they have different freezing points. (e.g., oil and water)

Distillation

A method of separating mixtures comprised of two or more pure liquids. It is a purification process where the components of a liquid mixture undergo a vaporization and condensation.

Distillate

the condensate that is collected in another container after distillation.

Centrifugation

The process of separating blood into red blood cells and plasma (and more) using a machine called centrifuge.
