What is the difference between vaporization and evaporation
Evaporation and Vaporization
Definition
Evaporation refers to a specific type of vaporization which occurs at temperatures below the boiling point of a liquid.
Vaporization (vaporisation) refers to a phase transition where a substance changes its phase from liquid to gas; it includes both evaporation and boiling.
Temperature
Evaporation occurs when the temperature of the liquid is below its boiling point.
Vaporization includes state changes from liquid to gas regardless of temperature—i.e. it includes the phase change occurring below, as well as at, the boiling point (Note that we cannot talk about vaporization above the boiling point. The temperature does not rise above the boiling point until all of the liquid has changed phase).
Pressure
Evaporation occurs when the vapor pressure is below external pressure.
Vaporization includes state change from liquid to gas when the vapor pressure is both below or equal to the pressure from the surroundings.
Location of Vaporizing Molecules
In evaporation, the molecules that vaporize are from the liquid surface.
In vaporization, the vaporizing molecules could come from below the surface when the liquid is boiling.
