Question
Comment on the following statements:
Rate of evaporation of an aqueous solution decreases with increase in humidity.
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.
