Write a note on: Saturation of air with vapour.

Explanation

i. When a given volume of air contains maximum possible water vapour, it is said to be saturated with vapour at that temperature.
ii. If the amount exceeds this limit, excess vapour is converted into water droplets.
iii. Dew drops, condensation of water droplets on the surface of water bottle taken out from refrigerator are some visible examples of air being saturated with water vapour.
iv. As saturation of air with vapour depends on the temperature of air, air saturated at a specific temperature becomes unsaturated if its temperature is increased
