(physics) The science of the conversions between heat and other forms of energy.

With regard to thermodynamics

thermodynamic

(physics) the state of a system in which its energy distribution is such that all parts of the system have the same temperature and no heat flows

(physics) Temperature defined in terms of the laws of thermodynamics rather than the properties of a real material: expressed in kelvins.

plural of thermodynamic temperature

Thermodynamics that studies a thermodynamic system as an ensemble of moving molecules, considering the macroscopic temperature as an average kinetic energy of the microscopic molecules.

Thermodynamics that studies a thermodynamic system as an undivided whole, described by macrostate variables such as volume, pressure and temperature, instead of considering the thermodynamic system as an ensemble of moving molecules.

(physics) A localized physical system consisting of interacting components, called degrees of freedom
