(B) Evaporation is a process in which liquid changes into vapor at any temperature below its boiling point.This process occurs only at the surface of the liquid because the particles at the surface have higher kinetic energy than the particles in the bulk of the liquid,allowing them to overcome the forces of attraction and escape into the atmosphere.Therefore,evaporation is considered a surface phenomenon.
