Difference Between Vaporization and Evaporation


というエントリーより備忘のため書き留めておきます。


Vaporization has three types:

Boiling, wherein the transition from liquid phase to gas phase takes place at or above the boiling temperature, and it occurs below the surface.

Sublimation, wherein the transition from solid phase to gas phase takes place without passing through a liquid phase, and it occurs at temperatures and pressures below the triple point of a substance.

Evaporation, wherein the transition from liquid phase to gas phase takes place below the boiling temperature at a given pressure, and it occurs on the surface.

Evaporation, therefore, is a type of vaporization of a liquid into gas on its surface. It is a part of the water cycle wherein solar energy causes the evaporation of water from oceans, seas, and other bodies of water as well as the moisture in the soil. When water is exposed to air, liquid molecules turn into vapor and rise up to form clouds where they are accumulated until such time that they are released back to earth as rain.

Summary:

1. Vaporization is a transitional phase of an element or compound from a solid phase or liquid phase to a gas phase while evaporation is a type of vaporization wherein the transition from a liquid phase to a gas phase takes place below the boiling temperature at a given pressure, and it occurs on the surface.

2. Vaporization changes the phase or state of matter from a solid or liquid to a gas while evaporation changes the liquid state of matter into a gas.

3. Vaporization can occur with boiling, sublimation, or evaporation while evaporation can happen with the right amount of heat, humidity, and air movement.
