Vaporization
Description
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. Th...

Vaporization is the transition from a liquid to a gas or vapor. For example, when heat energy is added to water, it reaches its boiling point and becomes steam.
The amount of energy needed to vaporize a given mass of liquid at a constant temperature is called the heat of vaporization.
Vaporization can also occur at the surface of a...
