Liquid water at 100oC and 1 bar has an internal energy (on an arbitrary scale) of 419 kJ/kg and a specific volume of 1.044 cm3/g. (a) What is its enthalpy? (b) The water is brought to the vapor state at 200oC and 800 kPa, where its enthalpy is 2838.6 kJ/kg and its specific volume is 260.79 cm3/g. Calculate ΔU and ΔH for the process.
