Liquid water at 453 K and 1002 kPa has an internal energy of 762 kJ/kg and a density of 890 kg/m3.

(a) What is the enthalpy (per weight and per volume)?

(b) We change the state to 573 K and 1500 kPA. The internal energy is now 2784 kJ/kg and the specic volume 169.7 cm3/g. What are ΔH and ΔU (per weight and per volume) ?
