![]() ![]() A thermodynamic model systemĭifferences in pressure, density, and temperature of a thermodynamic system tend to equalize over time. He showed that the thermodynamic entropy is k ln Ω, where the factor k has since been known as the Boltzmann constant.Ĭoncept Figure 1. Ludwig Boltzmann explained the entropy as a measure of the number of possible microscopic configurations Ω of the individual atoms and molecules of the system (microstates) which correspond to the macroscopic state (macrostate) of the system. Entropy is therefore also considered to be a measure of disorder in the system. The definition of entropy is central to the establishment of the second law of thermodynamics, which states that the entropy of isolated systems cannot decrease with time, as they always tend to arrive at a state of thermodynamic equilibrium, where the entropy is highest. Entropy predicts that certain processes are irreversible or impossible, despite not violating the conservation of energy. ![]() The term was introduced by Rudolf Clausius in the mid-19th century to explain the relationship of the internal energy that is available or unavailable for transformations in form of heat and work. In classical thermodynamics, entropy (from Greek τρoπή (tropḗ) 'transformation') is a property of a thermodynamic system that expresses the direction or outcome of spontaneous changes in the system.
