A rigid cylinder fitted with a freely floating piston is divided into two parts (A and B) by a rigid metal partition. Initially, part  contains 0.91 kg of water liquid and/or vapor) at 1.7 MPa and part B contains 0.45 kg of dry, saturated water vapor at 600 kPa. The piston and the sides of A and B are perfectly insulated. partition is a good heat conductor and allows enough heat transfer to keep the temperature of part A always equal to the temperature of part B. The bottom of part B is then heated until the pressure of part equals the pressure of part B. Determine the heat transfer (kJ) into the bottom of part B.
