Liquid water at 180oC and 1,002.7 kPa has an internal energy (on an arbitrary scale) of 762.0 kJ kg^-1 and a specific volume of 1.128 cm^3 g^-1.
A) What is its enthalpy?
B) The water is brought to the vapor state at 300oC and 1,500kPa, where its internal energy is 2, 784.4 kJ kg^-1 and it's specific volume is 169.7 cm^3 g^-1. Calculate deltaU and deltaH for the process.
