• Gibbs free energyRelated: Enthalpy supplies the energy contribution in the definition of Gibbs free energy.

• Transition stateRelated: Enthalpy changes help characterize the energetic cost of reaching a transition state.

• Latent heatRelated: At constant pressure, latent heat corresponds to the enthalpy change between phases.

• Activation energyRelated: Reaction enthalpy compares reactants and products, not the height of the activation barrier.

• Heat capacityRelated: At constant pressure, heat capacity is the temperature derivative of enthalpy.

• CalorimetryRelated: Constant-pressure calorimetry commonly determines enthalpy changes from measured heat.

• Internal energyRelated: At constant pressure, enthalpy change tracks energy transfer including expansion work.

• Flash evaporationRelated: An ideal throttling flash conserves enthalpy as pressure drops.

• Gibbs–Helmholtz equationRelated: At constant pressure, it supplies the energy term in the equation.

• Superheated steamRelated: Superheating raises steam’s enthalpy, which helps determine turbine work and heat requirements.

• ThermochemistryRelated: Reaction heat at constant pressure is measured as a change in this quantity.

• Endothermic processRelated: At constant pressure, an endothermic process has a positive enthalpy change.

• Exothermic processRelated: Its change is negative for an exothermic process at constant pressure.
