The temperature at which a solid substance undergoes fusion, changing from a solid to a liquid state. Contrast with freezing point.
The temperature at which a solid substance undergoes fusion, changing from a solid to a liquid state. Contrast with freezing point.

The temperature at which a solid substance undergoes fusion, changing from a solid to a liquid state. Contrast with freezing point.

At the melting point the solid and liquid phase exist in equilibrium. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point.

Because of the ability of some substances to supercool, the freezing point is not considered to be a characteristic property of a substance.

When the "characteristic freezing point" of a substance is determined, in fact the actual methodology is almost always "the principle of observing the disappearance rather than the formation of ice", that is, the melting point.
