Pressure. Temperature. Volume. These values can be both intensive and extensive magnitudes and are independent of the path taken to reach the current state. System state functions generally have a particular dependency on each other. State functions represent quantities or properties of a thermodynamic system, while non-state functions represent a process during which the state functions change. For example, the state function PV is proportional to the internal energy of an ideal gas, but the work W is the amount of energy transferred as … See more In the thermodynamics of equilibrium, a state function, function of state, or point function for a thermodynamic system is a mathematical function relating several state variables or state quantities (that describe equilibrium states of … See more It is likely that the term "functions of state" was used in a loose sense during the 1850s and 1860s by those such as Rudolf Clausius, William Rankine, Peter Tait, and William Thomson. … See more The following are considered to be state functions in thermodynamics: • Mass • Energy (E) • Entropy (S) See more • Media related to State functions at Wikimedia Commons See more A thermodynamic system is described by a number of thermodynamic parameters (e.g. temperature, volume, or pressure) which are not necessarily independent.
