The piston is initially resting on the stops . The cylinder contains carbon dioxide at 50 psia and 200 F and takes up 1 ft^3. The piston will float when the pressure is 100 psia. The cylinder is heated ,and when the piston just starts to float weights are added so that the gas undergoes a polytropic process with n=1.5 until the volume is 2 ft^3.
a. Draw the process on a PV diagram.
b. Find the work done in both steps.
c.Is the heat transferred positive or negative? With respect to what system?
