Explain EVAPORATION

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling, which, instead, occurs within the entire mass of the liquid and can also take place when the vapor phase is saturated, such as when steam is produced in a boiler. Evaporation that occurs directly from the solid phase, as commonly observed with ice or moth crystals (napthalene or paradichlorobenzine), is called sublimation.
