Question

the amount of water vapour in the air increase​

Answer 1

Answer:

If the amount of water vapor in the air increases, the relative humidity increases, and vice versa. However, relative humidity is dependent on air temperature, too. If the water vapor content stays the same and the temperature drops, the relative humidity increases.

Answer 2

The amount of water vapor in atmosphere determines the level of humidity. As the amount of water vapor in the atmosphere increases so does the level of humidity. Higher humidity levels result in excessive sweating and this sweat does not dry quickly leaving us feeling hot and sticky.
