A vertical piston-cylinder arrangement is filled with 1.0 liter of carbon dioxide at a temperature of 300 K and a pressure of 200 kPa. The piston area is 100 cm² and it rests on top of a set of stops and it is held down with a spring that has a spring constant of 20.000 N/m. In process 1-2, heat is added at constant volume until the pressure is 300 kPa. Then in process 2-3 the piston rises, compressing the spring until the volume is 1.5 liters. Complete the property table below for the two cases and construct P-v and T-v diagrams showing the two processes. For case A allow for variable specific heats and in case B use an appropriate average value of specific heats during each process. (Show relations and calculations used in addition to the table.)
