What do you understand by the term condensation? Explain any three forms of condensation.
Answers

Answer:
Water which collects as droplets on a cold surface when humid air is in contact with it
.Frost: When the water vapor present in the air is condensing and the temperature of the air is 0° or less, then the water vapor takes the form of a solid or snowflake that is the frost. For form to frost, it is necessary that the temperature of the air continues to drop rapidly for long and the sky is cloudless and the air contains water vapor and the temperature of the air is below the freezing point.
Fog: It originates from water vapor condensation near the surface. Fog reduces atmospheric transparency. When the visibility of the ground or the atmosphere decreases below 1 kilometer, then this form of condensed water vapor is called fog. It is necessary for the formation of fog that the temperature of the air falls below dew point and wind speed be slow. Depending on the visibility, the fog is of the following types: Light, simple, intensive and highly dense. The fog visibility is measured by the instrument named transmissometer. The condition of the visibility being slightly low is called fog
Clouds: The gigantic mass of water particles or snowflakes formed by the condensation of water vapor in the open air, at high altitude, is called cloud. Clouds are found up to a height of 12,000 meters. Cloud is formed at various altitudes from the surface of the Earth.So these are of different types. Therefore, on the basis of their height, density, expansion and transparency.
