It is a process in which a phase transition occurs from the liquid phase to the gaseous phase.
Principle of Evaporation:
Evaporation is a surface phenomenon.
It works on the principle that liquids vaporize easily while solid does not.
The transformation of the surface liquid particles into vapors is spontaneous.
The rate of evaporation of volatile liquids is higher than that of non-volatile liquids as their particles require very low thermal energy to escape as vapors.
