How will you differentiate between evaporation and boiling?

Evaporation

Boiling

1. It is slow process

1. It is a fast process

2. Evaporation occurs spontaneously at all temperatures.

2. Boiling occurs at the boiling point at which the vapour pressure of the liquid is equal to the atmospheric pressure. 

3. Evaporation takes place only at the surface of the liquid

3. Boiling involves the formation of bubbles of vapour below the surface of the liquid.

4. The rate of evaporation increases by increasing the surface area

4. Surface area has no effect on the rate of boiling.
