Question

What is condensation? What are its various forms?

Answer 1

When air temperature falls, the water vapour in the saturated air condenses into liquid or solid state. This process is termed as condensation. There are several forms of condensation. Some of them are as follows:

1. Clouds: They are formed when water vapour condenses over dust particles and forms water droplets.
2. Dew: It is formed when the water vapour comes in contact with cool surfaces like grass and leaf and forms tiny water droplets.
3. Fog: It results from the condensation of water vapour near the surface of the Earth.
5. Frost: Dew occurring in the form of ice crystals is known as frost.
