Thermodynamic free energy - Wikipedia

WebEntropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. Although all forms of energy can be used to do work, it is not possible to use the entire available energy for work. WebIn physics, a partition function describes the statistical properties of a system in thermodynamic equilibrium. [citation needed] Partition functions are functions of the thermodynamic state variables, such as the temperature and volume.Most of the aggregate thermodynamic variables of the system, such as the total energy, free energy, entropy, … WebJan 1, 2006 · N A Williams.
