Question

what will happen if the amount of water vapour in the air increases

Answer 1

This percentage tells you how close the airis to being saturated. ... If the amount of water vapor in the air increases, the relative humidity increases, and if the amount of water vapor in the air decreases, the relative humidity decreases. However, relative humidity is dependent on air temperature, too.

Answer 2

If the amount of water vapour in the air increase ,the relative humidity increase and if the amount of water vapour in air decrease then relative humidity decrease.
