The 26 pages that link to State function, each with the reason it gives.

• EntropyNarrower topic: Entropy change depends on endpoints even when the actual process is irreversible.

• Gibbs free energyNarrower topic: Gibbs free energy is a state function, so its change depends only on endpoints.

• First law of thermodynamicsNarrower topic: Internal energy is a state function, so its change depends only on endpoints.

• EnthalpyNarrower topic: Enthalpy’s path independence distinguishes it from heat and work.

• Heat capacityNarrower topic: Heat capacity is defined from changes between states, with the process constraint specified.

• Reversible processNarrower topic: State functions make endpoint comparisons possible even when reversible and irreversible paths differ.

• Clausius–Clapeyron relationNarrower topic: Entropy and volume changes are state differences, making the relation independent of transition path.

• Thermodynamic potentialNarrower topic: Thermodynamic potentials are state functions, unlike heat and work.

• Free energyNarrower topic: Free energy is determined by the system's state, allowing changes to be calculated from endpoints.

• Maxwell relationsNarrower topic: The relations apply to derivatives of state functions rather than arbitrary path-dependent quantities.

• Hess's lawNarrower topic: Its path independence is the thermodynamic basis of Hess's law.

• Fundamental thermodynamic relationNarrower topic: Internal energy and entropy are state functions, so their differentials describe state changes.

• Gibbs–Helmholtz equationNarrower topic: The equation relates state functions rather than process-dependent heat or work.

• Endothermic processNarrower topic: Enthalpy change is path-independent even when the process’s heat transfer depends on conditions.
