Common thermodynamic equations and quantities in thermodynamics, using mathematical notation, are as follows: List of thermodynamic propertiesThermodynamic potentialFree entropy and Defining equation (physical chemistry) Many of the definitions below are also used in the thermodynamics of chemical reactions. Heat capacity and Thermal expansion Thermal conductivity The equations in this article are classified by subject. where kB is the Boltzmann constant, and Ω denotes the volume of macrostate in the phase space or otherwise called thermodynamic probability. for reversible processes only Below are useful results from the Maxwell–Boltzmann distribution for an ideal gas, and the implications of the Entropy quantity. The distribution is valid for atoms or molecules constituting ideal gases. Corollaries of the non-relativistic Maxwell–Boltzmann distribution are below. For quasi-static and reversible processes, the first law of thermodynamics is: where δQ is the heat supplied to the system and δW is the work done by the system. Thermodynamic potentials Maxwell relations The following energies are called the thermodynamic potentials, and the corresponding fundamental thermodynamic relations or "master equations" are: The four most common Maxwell's relations are: More relations include the following.

Thermodynamic equations
Thermodynamics is expressed by a mathematical framework of thermodynamic equations which relate various thermodynamic quantities and physical properties measured in a laboratory or production process. Thermodynamics is based on a fundamental set of postulates, that became the laws of thermodynamics. One of the fundamental thermodynamic equations is the description of thermodynamic work in analogy to mechanical work, or weight lifted through an elevation against gravity, as defined in 1824 by French physicist Sadi Carnot.
