Evaporation is the process of changing phases from a liquid to a gas or vapour that is a type of vaporisation of a liquid from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The Evaporation can occur directly from the solid phase below the melting point, as commonly observed with ice at or below freezing or moth crystals, is called sublimation. The other type of vaporization is boiling, which is characterised by bubbles of saturated vapour forming in the liquid phase.
