Question

Decrease in humidity at a given temperature increases the rate of evaporation.

• A. True
• B. False

Answer 1

The correct option is A

True

A decrease in humidity means less amount of water vapor in the atmosphere. So when less water is present in the atmosphere, water vapors from a source, say wet clothes or a pan full of water, have more tendency to go in the atmosphere due to the difference in concentration. The increased tendency to leave the surface of the source in the form of vapor is nothing but evaporation.
