Question

Define evaporation. Describe how it is used for separating mixtures.

Answer 1

the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure is called evaporation.

evaporation is used to separate mixtures in which one component is volatile while the other is not.

or it can be used when one component is more volatile than the other such that when they heated they evaporate at different temperature.
