• Is the branch of physics that describes the equilibrium states at the macroscopic level. • Thermodynamics offers a formal apparatus applies only to equilibrium states, defined as a state to "any system which tends to evolve and characterized in the same all system properties are determined by intrinsic and not previously applied by external influences."
• Equilibrium states are studied and defined by extensive quantities such as internal energy, entropy, volume or molar composition of the system or through non-extensive magnitudes derived therefrom such as temperature, pressure and potential chemical; other quantities such as magnetization, the electromotive force and associated with the mechanics of continuous media in general can also be treated by thermodynamics.
