Dew, Fog and Clouds are the three major forms of condensation
(a) Dew:
It is a water droplet formed by the condensation of water vapour on a relatively cold surface of an object. It forms when the temperature of an object drops below the dew point temperature.
Frost:
The ice crystals formed by deposition of water vapour on a relatively cold surface of an object is known as frost.
(b) Fog:
Fog is the suspended tiny water droplets or ice crystals in an air layer next to the earth’s surface that reduces the visibility to 1,000 m or lower.
Mist:
Mist is the tiny droplets of water hanging in the air. These droplets form when the water vapour in the air is rapidly cooled, causing it to change from invisible gas to tiny visible water droplets.
(c) Clouds:
Clouds consist of tiny water droplets/ice particles which are so small and light in weight. Clouds are formed by microscopic drops of water or by small ice crystals.
