Moran and Shapiro, Problem 3.23 and 3.39, modified. Two kg of Refrigerant 134a undergoes a polytropic process (p×Vn = constant) in a piston-cylinder assembly from an initial state of saturated vapor at 2 bar to a final state of 12 bar, 80 C. Determine the work for the process. Also, determine the heat transfer that must occur, in kJ. Hint: You will have to determine the polytropic exponent n. Repeat your calculations if the final state is, instead, 12 bar and saturated vapor. The polytropic exponent n will be different, of course
