What is condensation? Explain these different forms of condensation: fog, mist, and dew
Answers
Condensation is the transformation of water vapour into solid or liquid state where the air is saturated with water and temperature falls.
In easy words , the transfer of gaseous state into liquid or solid is Condensation.
★
→ When water vapour condenses on cold surface it formed Dew.
★
→ When the condensation occurs around this particles in the lower layers of atmosphere it leads to the formation of fog or mist.
★
→ When the temperature drops below the freezing point, saturated air condenses to form ice crystals called as frost.
Condensation
It is the transformation process in which water vapour becomes liquid. It is the opposite process of evaporation. In the evaporation process water, converts into vapour.
Dew:
It forms when moisture settles in the form of water droplets on colder surfaces of objects, which are in a solid state. The dew point should be higher than the freezing point so that dew will occur.
Fog:
The difference between mist and fog is, the mist has a higher moisture content. Each nucleus in mist has a thicker covering of moisture on it. Fogs are drier than mist, and they form when warm air currents collide with cold air currents.
Mist:
These are common over mountains as warm air rises the slopes and collides with a chilly surface. Water droplets also create mist. It implies that the mist is less dense and dissipates more quickly.
