Question

both the process of evaporation and boiling involves the change of state from liquid to gas but still they are different from each other. justify

Answer 1

1. Evaporation occurs on the surface of the liquid whereas boiling occurs at the entire length of liquid.
2. Boiling occurs rapidly whereas evaporation occurs slowly.
3. Evaporation occurs at any temperature whereas boiling occurs at a specific temperature.
4. The motion of particles is fast in boiling whereas in evaporation few particles move slowly and few at a faster rate.
5. There is formation of bubbles in boiling, but bubbles are not seen in evaporation.

Answer 2

they are different because boiling occurs at particular temperature that is boiling point whereas evaporation take place when liquid is placed in an open container at any temperature below its boiling point .Boiling is bulk phenomenon and evaporation is the surface phenomenon
