Sensible Heat

It is common sense that heat flows from an object at a higher temperature to one at a lower temperature. Heat , like work, is a transfer of thermal energy rather than the flow of a substance.

See Main Article Sensible heat

Latent Heat

Latent heat is amount of heat being absorbed or released during phase change. The heat required to melt a solid substance of unit mass is defined as the latent heat of fusion. The heat required to vaporize a liquid substance of unit mass is defined as the latent heat of vaporization.

See Main Article Latent Heat

Phase Change

When a process involves a change in phase, the heat absorbed or released can be expressed as the product of the mass quantity and the latent heat of the material.

See Main Article Phase change
