Thermodynamics is the physics of energy, heat, work, entropy and the spontaneity of processes. It is closely related to statistical mechanics from which many thermodynamic relationships can be derived. Thermodynamics usually refers to equilibrium thermodynamics of quasistatic processes. Time-dependent thermodynamic processes are studied by non-equilibrium thermodynamics.
