Question

Rate of evaporation increases with:

• A. Increase of surface area.
• B. Increase of temperature.
• C. An increase in wind speed.
• D. All the options are correct.

Answer 1

The correct option is D

All the options are correct.

Evaporation is a surface phenomenon, therefore increase in surface area increases the rate of evaporation.
With the increase in temperature more number of particles gets enough kinetic energy to go into the vapour state.
The decrease in humidity i.e. water vapour present in the air decreases at a given temperature and it results in the increase of the rate of evaporation.
With the increase in wind speed, the particles of water vapour move away with the wind which increases the rate of evaporation.
