Difference between Evaporation and Vaporisation

Both the processes convert liquid into gaseous state but there are four major differences between the two processes.

  • Evaporation takes place at all temperature but vapourisation takes place only at a fixed temperature which is the boiling point of the liquid.
  • Evaporation is a slow and gradual process whereas vapourisation is a rapid and violent process.
  • Evaporation takes place only at the surface of the liquid whereas vapourisation takes place over the entire liquid.
  • Evaporation causes cooling but vapourisation does not produce cooling.
