Thermodynamics

Thermodynamics is a branch of physics concerned with heat and temperature and their relation to other forms of energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question.

Thermodynamics has its basic concern the transformation of heat into mechanical energy. Thus, it plays a central role in technology, because almost all the "raw" energy available for our use is in the form of heat.
