Question

The percentage of water vapour in the air is always the same. Do you agree? Give reasons.

Answer 1

No, the percentage of water vapours in the air is not always same. The percentage of water vapour varies from time to time and from place to place. The amount of water vapour present in the air depends on a number of factors such as temperature and temperature changes from one place to another. This results in variable composition of water vapour in the air.
