VAPOURIZATION

 "Vapourization of an element or compound is phase transaction from liquid or solid phase to gas phase."



There are three types of vapourization.

  1. Evaporation
  2. Boiling
  3. Sublimation
1.Evaporation:
                       Evaporation is a phase transition from liquid to gas phase at temperature below the boiling temperature. Evaporation usually occurs on surface.

2.Boiling:
              Boiling is a phase transition from liquid to gas phase that occurs at or above the boiling temperature.
Boiling occurs on surface.


3.Sublimation:
                     Sublimation is the transition of a substance from solid to gas phase without passing through an intermediate liquid phase.the reverse process of sublimation is called deposition.formation of frost is example of meterological depositon.
