WebA system's enthalpy is a thermodynamic attribute. It's the product of the system's pressure and volume multiplied by internal energy. It indicates the ability to perform non-mechanical labor and the ability to dissipate heat. H stands for enthalpy, while h stands for specific enthalpy. The Joule and Calorie are standard units for expressing ... WebEnthalpy is defined as follows. H = E + PV. Enthalpy is the sum of the internal energy. and pressure times volume. We cannot measure the enthalpy of a system, but we can look …
