Problem
1. A cylinder fitted with a frictionless piston contains 2 kg of superheated refrigerant R-134a vapor at 350 kPa, 100oC. The cylinder is now cooled so that the R-134a remains at constant pressure until it reaches a quality of 75%. Calculate the heat transfer in the process.
2. A piston/cylinder contains 1.5 kg of water at 200 kPa, 150oC. It is now heated by a process in which pressure is linearly related to volume to a state of 600 kPa, 350oC. Find the final volume, the heat transfer, and the work in the process.
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.
