Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body. Rate of evaporation depends on.
