What are the types of vaporization?

Evaporation and boiling are two vaporization types. Evaporation involves the change of the phase of an element from liquid to gas, at temperatures lower than its boiling point, at a given pressure. Boiling involves a change of phase from liquid to gas at a temperature higher than its boiling point.

In the evaporation process, the molecules present on the surface of the liquid gain adequate kinetic energy and defeat the inter-molecular forces between them when they move in the appropriate direction. Boiling occurs when the vapor pressure of the liquid is the same as the pressure of the surrounding environment.
