Question

what is the difference between vapourization and evaporation?

Answer 1

 Vaporization is the process of changing a liquid to its vapors at a temperature below its boiling point. Evaporation is the process of changing a liquid to its vapors at its boiling point.Vaporization> Vaporization is a spontaneous process which occurs at the surface of a liquid. It is the conversion of a liquid to its vapor; it is the reverse of the process of condensation. 
Evaporation> Evaporation is a phase transition, where liquid phase changes to its gas phase at its boiling point.

Vaporization is a slow and silent process. Evaporation is a speed and violent process.During the vaporization, temperature of the liquid changes. During the evaporation, temperature is a constant

Answer 2

simply we can say , that vapourisation is a forced process of converting liquid to gaseous state , keeping away from the atmosphere. But whereas evaporation is a natural process of conversion of liquid to gaseous state in nature
