Evaporation and distillation are used for various reasons. There are quite a lot of difference between them.
Evaporation involves a change in the state of matter. Evaporation is a natural process.
Evaporation is a process where liquid changes it states into gas. Factors that affect evaporation include pressure, temperature, and surface area etc.
During the process of distillation, evaporation can happen. Also, during evaporation, the liquid vaporizes below its boiling point.
Distillation is a method used to separate compounds from mixtures. Distillation is based on the difference of boiling points of the different components. The process of distillation is rapid. With the use of distillation, liquid can be separated or purified. Lastly, distillation cannot take place within the process of evaporation.
