WebSep 9, 2024 · Well, let us see how the enthalpy changes if we change the pressure and volume (and hence the internal energy) of a system. We'll just differentiate Equation 9.1.1. (9.1.2) d H = d U + P d V + V d P. But d U = T d S − P d V, and so the first law becomes. (9.1.3) d H = T d S + V d P. This helps us to see a little more the meaning of enthalpy.

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.
