A rigid tank A of volume 0.6 m3 contains 3 kg of water at 120 ° C and the rigid tank B of V = 0.4m3 contains water at 600 kPa and 200 ° C. The tanks are connected to a cylinder-piston system initially empty when the valves are closed. The pressure in the cylinder must be 800 kPa for the piston to float. Now the valves open slowly and heat is transferred so that the water reaches a uniform state of 250 ° C with the valves open. Find the final volume and final pressure, work, and heat transferred during the process.

In a piston-cylinder assembly, there is initially 2 kg of water at a temperature of 25 °C and a pressure of 100 kPa. Then heat is given to the water until its volume is 0.4 m3. At this point, the piston in the cylinder is fixed with a stopper, but the water in the cylinder continues to heat until its temperature reaches 300 oC. According to this, calculate a) the final pressure of the water, b) the amount of heat given to the water, c) the work done by the piston. d) Show these processes in the T-v (Temperature-Specific Volume) diagram

While the piston is pinned, a cylinder with a volume of 0.05 m3 contains 200 kPa pressure and 300 K air temperature. Since the pressure is 0.4 MPa as a result of the heat transfer from the environment, the pin breaks and when the system becomes thermodynamically equilibrium, its volume becomes 0.1 m3.

wo springs with same spring constant are installed in a massless piston/cylinder with the outside air at 100 kPa. If the piston is at the bottom, both springs are relaxed and the second spring comes in contact with the piston at V = 2 m3. The cylinder contains ammonia initially at -2°C, x = 0.13, V = 1 m3, which is then heated until the pressure finally reaches 1200 kPa. At what pressure will the piston touch the second spring? Find the final temperature and the total work done by the ammonia.
A pressure cooker operates by cooking food at a higher pressure and temperature than is possible at atmospheric conditions. Steam is contained in the sealed pot, with a small vent hole in the middle of the cover, allowing steam to escape. The pressure is regulated by covering the vent hole with a small weight, which is displaced slightly by the escaping steam. Atmospheric pressure is 1 bar, the vent hole area is 7mm2, and the pressure inside should be 2.75 bar. What is the mass in kg of the small weight?
