Chapter 2, Problem 2.19(choose chapter or problem)
Liquid water at 180°C and 1002.7 kPa has an internal energy (on an arbitrary scale) of \(762.0 kJ \cdot kg^{−1}\) and a specific volume of \(1.128 cm^{3} \cdot g^{−1}\).
(a) What is its enthalpy?
(b) The water is brought to the vapor state at 300°C and 1500 kPa, where its internal energy is \(2784.4 kJ \cdot kg^{−1}\) and its specific volume is \(169.7 cm^{3} \cdot g^{−1}\). Calculate ΔU and ΔH for the process.
