EVAPORATION

VAPOURIZATION

Liquid changes to gaseous phase at temperature below boiling point

Solid or Liquid changes to gaseous phase at boiling point or below the boiling point . It may be further classified as evaporation and boiling

It is a surface phenomenon , only particles at the surface participate in evaporation

It is a surface phenomenon in case of evaporation and bulk phenomenon in case of boiling where all the particles in the matter participate

Evaporation results in lowering of temperature

The temperature may be lowered or remains constant in vaporization

Vapour pressure is lower than external pressure

Vapour pressure may be lower or same as external pressure in evaporation and boiling respectively

Heat source is not required for the process

A heat source may or may not be required depending on the process

 

Evaporation and Boiling are the two classifications of vaporization-Teachoo-01.jpg
