5. (14 points) An insulated cylinder is initially filled with 0.015 m³ H2O steam at 300 kPa and 200°C. The steam is now compressed in a reversible manner until 1.4 MPa. (5a). (2p) Is this process isentropic? Explain! (5b). (6p) Please determine the specific entropy at the initial and final states. (5c). (6p) Please find the work transfer during this process, in kJ.
