1) [20] 150 g of Refrigerant R-22 in a piston-cylinder assembly undergoes quasistatic, constant- pressure heat removal. Kinetic and potential energy changes of the R-22 are negligible. Initially, the R-22 is at 20 C and 4 bar. At the end of the process, the R-22 is saturated vapor. a) Sketch the process on a p-v diagram that shows the vapor dome. Sketch the process on a p- T diagram that also shows the saturation line. b) Find the heat transfer into the R-22 during the process (expected to be a negative number) and the work done by the R-22 during the process
