Answer
Condensation is the process by which water vapour changes into tiny water droplets on cooling.
Condensation occurs when moist air cools to its dew point or when additional water vapour is added to saturated air. During this process, the latent heat stored in water vapour is released into the atmosphere, and the water vapour condenses around dust or salt particles (condensation nuclei) to form tiny water droplets, leading to the formation of clouds, fog, dew, or rain.
