Liquid water at 453K and 1002 kPA has an internal energy of 762 kJ/kg and a density of 890 kg/m^3 a) what is the enthalpy (per weight)? b) We change the state to 573K and 1500 kPA. The internal energy is now 2784 kJ/kg and the specific volume 169.7 cm^3/g. What is the change in enthalpy (delta H) and change in internal energy (delta U) (per weight)?
