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 [1] (e.g. gas, liquid
30 sty 2023 · A state function is a property whose value does not depend on the path taken to reach that specific value. In contrast, functions that depend on the path from two values are call path functions.
Learn about state functions, which are properties of a system that depend only on the state of the system and not on the path by which the state is achieved. Find definitions, examples, and applications of state functions such as internal energy, enthalpy, and entropy.
10 sty 2023 · For a state function, each infinitesimal step that we add together by the process of integration is called an exact differential. When integrated, the sum of exact differentials is a value that is independent of path, depending only on the initial and final states.
A state function is a thermodynamic quantity that depends only on the present state of a system and not on how the system arrived at that state. Learn the list of state functions, their change formula, integral form, and examples with adiabatic and isothermal processes.
Learn the definitions and examples of state variables and functions, derived quantities and densities, and the zeroeth law of thermodynamics. Explore the concepts of extensive and intensive variables, and how they relate to heat and work.
Learn what state functions are and how they differ from path functions in thermodynamics and thermochemistry. See examples of state variables, such as temperature, pressure, and entropy, and watch videos explaining state functions.
