Problem
A piston/cylinder has 2 lbm of R-134a at state 1 with 200 F, 90 lbf/in.2, and is then brought to saturated vapor, state 2, by cooling while the piston is locked with a pin. Now the piston is balanced with an additional constant force and the pin is removed. The cooling continues to state 3, where the R-134a is saturated liquid. Show the processes in a P-V diagram and find the work and the heat transfer in each of the two steps, 1 to 2 and 2 to 3.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
