What is the difference between Evaporation and Vaporization?

Many people consider vaporization and evaporation the same term but in reality, both are different terms. One common point between these 2 terms is that in both terms liquid change in the gaseous state.

Evaporation

Evaporation is the process in which water changes in the gaseous state due to the rise in temperature or pressure.

Vaporization

The vaporization process is the process in which liquid changes into the gaseous state when the temperature reaches above the boiling point.

At any time when the molecules of water absorb energy from surrounding and change in the gaseous form by cooling the area from where molecule evaporated is said to be evaporation process. The vaporization process occurs only in 1 condition when the liquid boils above its boiling point.

What is the difference between Evaporation and Vaporization?

Key Difference

  • Vaporization occurs during the boiling or sublimation process whereas the Evaporation process mostly occurs below the boiling point of the liquid.
  • Vaporization changes the state of matter from solid or liquid to the gaseous state whereas Evaporation used to change the liquid directly to the gaseous state.
  • Vaporization requires less energy and it is a fast process whereas Evaporation is the slow process.
  • All water changes in the gaseous state in the vaporization process whereas in evaporation water from the top change in the gaseous state.
  • During the process of Vaporization molecules come from below to the surface during boiling whereas, during the process of Evaporation, molecule vaporizes from the surface of the water.
