Question

What are forms of condensation? Describe the process of dew and frost formation.

Accepted Answer

Condensation: Condensation is the process of conversion of water vapour into water.It is caused by the loss of heat. When moist air is cooled, it may reach a level when its capacity to hold water vapour come to an end. Then, the surplus water vapour condenses into liquid form. On the basis of temperature and location forms of condensation can be of different types as-Dew, frost, fog and mist, smog or clouds

(i) Dew: It is the moisture settling on cooler surfaces of solid objects such as stones, grass blades and plant leaves in the form of water droplets.For the formation of dew, the dew point should be above the freezing point.

(ii) Frost:When condensation occur below freezing point (CPC), i.e. the dew point is at or below the freezing point the formation of frost takes place on cold surfaces.Frost is formed when the temperature of air falls rapidly so the water vapour directly turns into solid particles rather than turning into liquid state.
