Q2: One mole of air at P: and temperature Ti is compressed at constant volume till its pressure doubled. Then it is allowed to expand reversibly and isothermally to the original pressure and finally restored to the originol temperature by cooling at constant pressure. Sketch the processes on a P-V and calculate the net work done by the

Two rigid tanks are filled with water. Tank A is 0.2 m³ at 100 kPa, 150°C and tank B is 0.3 m³ at saturated vapor 300 kPa. The tanks are connected by a pipe with a closed valve. We open the valve and let all the water come to a single uniform state while we transfer enough heat to have a final pressure of 300 kPa. Give the two property values that determine the final state and find the heat transfer. B A
