WebSep 9, 2024 · Recognizing that the work done in a reversible process at constant pressure is. wrev = − PΔV, we can express Equation 13.4.3 as follows: ΔU = qrev + wrev = TΔS − PΔV. Thus the change in the internal energy of the system is related to the change in entropy, the absolute temperature, and the PV work done.
