Answer
The two ways to change liquid state to vapour state are:
- Boiling
- Evaporation
Differences between Boiling and Evaporation are listed below:
| Boiling | Evaporation |
|---|---|
| Boiling takes place at fixed temperature. | Evaporation takes place at all temperatures. |
| Boiling is a rapid process. | Evaporation is a slow process. |
| Boiling takes place throughout the mass of the liquid at the same instant. | Evaporation takes place only from the surface of the liquid. |
| In boiling, external heat is supplied. | In evaporation, liquid molecules absorb heat from its surroundings to convert into vapour state. |
