Two kilograms of water is contained in a piston-cylinder device where a linear spring is attached to the piston, as shown in the figure. The spring was initially at rest, when the pressure of water inside the cylinder was 100 kPa and the volume was 0.2m³. Heat is then added to the system. As the piston first hits the stops, it is known that the volume was 0.8 m³ and the temperature was 600°C. The heating is continued until the pressure reaches 1.2 MPa. Determine the final temperature, sketch the process on a P-V diagram, and calculate the work done during the entire process. H,0

The piston/cylinder device contains 0.5 kg of water at a temperature of 200 0C and pressure of 0.8 MPa. The water undergoes an isobaric process until it becomes saturated liquid. Find the total work done in the process. Is it work done on the system or by the system?

Determine the work done by the expanding gas using the trapezoidal rule. from the data in the image

Refrigerant 134a expands in a piston-cylinder assembly from p₁= 200 lb/in² and T₁ = 140°F to p₂ = 30 lb/in² and T₂ = 80 °F. The mass of refrigerant is 0.46 lb. During the process, the work done by the refrigerant is 4.32 Btu. Kinetic and potential energy effects are negligible. Determine the initial volume of the refrigerant, V₁, in ft³, and the heat transfer for the process, in Btu. Step 1 * Your answer is incorrect. Determine the initial volume of the refrigerant, V₁, in ft³. V₁= 0.105743 ft3
