Explanation for the phenomenon of evaporation of water has to be given. Concept introduction: The phenomenon of evaporation of liquid is transition from “ liquid phase ” to “ vapo r phase ”. Almost all the liquids have the tendency to evaporate either spontaneously at room temperature without the effect of “ external energy ” or in the presence of external energy like heat etc. If a liquid evaporates spontaneously at room temperature then it is called “ volatile liquid ”. Examples include diethyl ether, chloroform, acetone etc. Non-volatile liquids do not evaporate at room temperature. They need external energy in the form of heat in order to increase the energy levels of the molecules to convert into vapor phase.
