Question

Evaporation is a surface phenomenon.

• A. True
• B. False

Answer 1

The correct option is A

True

In evaporation, only the molecules of the liquid present on the surface of the liquid leave the liquid state and change into vapour state. It does not affect the molecules present in the bulk of the liquid. Thus, evaporation is a surface phenomenon. If the surface area increases, the rate of evaporation also increases.
