Enthalpy /ˈɛnθəlpi/ (
listen), a property of a thermodynamic system, is equal to the system's internal energy plus the product of its pressure and volume.[1][2]In a system enclosed so as to prevent mass transfer, for processes at constant pressure, the heat absorbed or released equals the change in enthalpy.
The unit of measurement for enthalpy in the International System of Units (SI) is the joule. Other historical conventional units still in use include the British thermal unit (BTU) and the calorie.
Enthalpy comprises a system's internal energy, which is the energy required to create the system, plus the amount of work required to make room for it by displacing its environment and establishing its volume and pressure.[3]
Enthalpy is defined as a state functionthat depends only on the prevailing equilibrium state identified by the system's internal energy, pressure, and volume. It is an extensive quantity.
