Web ResultJan 30, 2023 · Enthalpy ( H H) is the sum of the internal energy ( U U) and the product of pressure and volume ( PV P V) given by the equation: H = U + PV (1) (1) H = U + P V. When a process occurs at constant pressure, the heat evolved (either released or absorbed) is equal to the change in enthalpy.
