20 kg of water at 200 kPa with a quality 25% is heated under a constant volume process until its pressure reaches 400 kPa. Determine: (a) Temperature, quality, and the volume in m^3 of the final state. (b) Qualitatively plot the process on P-v and P-T diagrams. (c) The specific internal energy in kJ/kg at the initial state and final state. (d) The overall change of internal energy in kJ, i.e. deltaU = U2 - U1
