Q-3/A vessel is divided equally in two parts. The first part is evacuated, while the second part of the tank contains 2.5 kg of compressed liquid water at a pressure of 4 bar and temperature 33 kelvin. The partition is now removed, and the water expands to fill the entire tank. During this process, estimate the entropy change of water and the heat, if the final pressure in the tank is 40 kPa.

R-134a enters a compressor as a saturated vapor at 80 kPa and exits at a pressure of 400 kPa. If 44 kJ/kg of work is required and 5 kJ/kg of heat is lost to the surroundings. What is the outlet temperature. Round your answer to the nearest whole number.
The case of a piston-cylinder device provided with stops is presented. Initially, the water supports the weight of the piston, and the force of the atmosphere is 300 kPa and 0.4 m3/kg. The water is heated until it reaches a saturated steam condition and the plunger rests on the stops. With the piston on the stops, the water is heated to a pressure of 700 kPa. Plot the curves of the processes on the p-V and T-V diagrams indicating the initial and final states of the guide. On both the p-V and T-V diagrams plot the isotherms passing through both states, and show their values in °C.
