WebSep 16, 2024 · ΔH = ΔU + PΔV = qp + w − w = qp. The subscript p is used here to emphasize that this equation is true only for a process that occurs at constant pressure. From Equation 5.4.7 we see that at constant pressure the change in enthalpy, ΔH of the system, is equal to the heat gained or lost. ΔH = Hfinal − Hinitial = qp.
