A state function depends only on the start and endpoint, and not the path. Example of state function: Few examples of state functions are, Internal energy (U) Enthalpy (H) Entropy (S) Gibbs energy Pressure Temperature
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 a system) that depend only on the current equilibrium thermodynamic state of the system (e.g. gas, liquid, solid, crystal, or emulsion), not the path which the system has ta…
