10 [kg] of refrigerant 134a contained in a piston-cylinder assembly undergoes a polytropic process for which Pvn = Constant. The initial and final states of the refrigerant are: P1= 240 [kPa], T1= -5 [oC], and P2= 960 [kPa], T2= 70 [oC], respectively. Determine the work and heat transfer for the process, each in [kJ].
