What Is Evaporation?

Evaporation :-The process of a liquid changing into vapour even below its boiling point is called evaporation.

Temperature
The rate of evaporation increasing the temperature of
the liquid. The rate of evaporation of a
liquid can be increased by heating it.

Surface Area of the Liquid
The rate of evaporation increases on increasing the surface area on the liquid.
The rate of evaporation can be increased by increasing the
surface of the liquid.

Humidity of Air
When the humidity of air is low , then the rate of
evaporation is high, and water evaporates more readily.
When the humidity of air is high, then the rate of
evaporation is low, and water evaporates very slowly .

Wind Speed
The rate of evaporation of a liquid increases with increasing
wind speed.
