Solution
The amount of water present in the air is known as humidity. If the water vapour in the air is already present in a large amounts, it is not able to take up more water through evaporation. Hence, the rate of evaporation of water will decrease. On a dry day, the air absorbs water more readily hence, the rate of evaporation is high on a dry day.
