Question

The process of conversion of gas into liquid on cooling is called as:

• A. evaporation
• B. condensation
• C. diffusion
• D. sublimation

Answer 1

The correct option is B condensation

Condensation is the change of water from its gaseous form, water vapour into liquid water.

It generally occurs in the atmosphere when warm air rises, cools and loses its capacity to hold water vapour. Excess water vapour condenses to form cloud droplets.

Hence, option $B$ is correct.
