R-134a in piston-cylinder arrangement is at 700 kPa and 80 degrees celcius. It is now cooled at a conswtant pressure to saturated liquid (state 2), at which point the piston is locked with a pin. The cooling continues to -10 degrees celcius (state 3). Show the processes 1 to 2 and 2 to 3 on one P-v and one T-v diagram.
