An insulated piston-cylinder device contains 0.05 m3 of saturated R-134a vapor at 0.8 MPa. The refrigerant is now allowed to expand in a reversible manner (i.e. isentropic) until the pressure drops to 0.4 MPa. Determine (a) the final temperature in the cylinder and (b) the work done by the refrigerant.

2 lbm of water at 300 psia completely fill a weighted piston-cylinder device whose volume is 2.5 ft3. The water is then heated at constant pressure until the temperature reaches 500°F. Determine the resulting change in the water's total entropy in Btu/R.
A 0.073-m3 piston-cylinder device contains 0.15 kg of Argon. Weights are placed on top of the piston so that the initial pressure inside the cylinder is at 335 kPa. Now weights are removed one-by-one until the final volume is 3.00 times that of the initial volume. During this process, the argon's temperature is maintained constant. Determine the final pressure in the device. Round your answers to one decimal place. kPa

1-A piston-cylinder device with a set of stops contains 10 kg of refrigerant-134a. Initially, 8 kg of the refrigerant is in the liquid form, and the temperature is 8°C. Now heat is transferred slowly to the refrigerant until the piston hits the stops, at which point the volume is 400 L. Determine (a) The temperature when the piston first hits the stops and (b) The work done during this expansion process. Also, show the process on a P-V diagram.
Example # 01 4-43 100-kg of R-134a at 200 kPa are contained in a ps ton-cylinder device whose volume is 12.322m.The piston is now moved until the volume is one-half its ornginal size.
