Differentiate between Evaporation and distillation.
EVAPORATION | DISTILLATION |

1. The process of obtaining vapours of liquid by heating it. | 1. The process by which a soluble liquid can be separated from a solution by first converting it into vapours by evaporation and then cooling and collecting the vapours by condensation in another container is called distillation. |
2. It is a natural phenomenon. | 2. It is an artificially designed method of separation. |
3. The method is used to separate dissolved salts from pure liquid. | 3. The process is used to separate not only dissolved solids from a liquid but also separate two miscible liquids from each other. |
4. For example - evaporation of water to obtain salt from seas. | 4. For example - the distillation of tap water to obtain distilled water for use in chemical reactions. |
