QUESTION:

Five kg of water is contained in a piston–cylinder assembly, initially at 5 bar and \(240^{\circ} \mathrm{C}\). The water is slowly heated at constant pressure to a final state. If the heat transfer for the process is 2960 kJ, determine the temperature at the final state, in \(^{\circ} \mathrm{C}\), and the work, in kJ. Kinetic and potential energy effects are negligible.
