4. Calculate q, w, △U, and △H for the process in which 2.5 mole of water undergoes the transition H2O (l, 373K) → H2O (g, 573K) at 1 bar of pressure. The Volume of liquid water at 373K is and the molar volume of steam at 373 and 573K is 4.33 and , respectively. For steam, Cp,m can be considered constant over the temperature interval of interest at
