Question

Give reasons to explain why it takes longer to dry wet clothes in humid weather.

Answer 1

Humidity is the amount of water vapour present in air. The air around us cannot hold more than a definite amount of water vapour at a given temperature. If the amount of water in air is already high, the rate of evaporation decreases.

Now on a humid day, the air already has sufficient amount of water vapour present. As a result, the rate of evaporation decreases and hence it takes longer to dry wet clothes.
