Ten kilograms of R-134a at

700kPa

are contained in a piston-cylinder with an initial volume of

0.08m^(3)

. The cylinder is heated isobarically until the refrigerant reaches a temperature of 30

\\\\deg C

. The R-134a then undergoes an adiabatic and reversible expansion to a final temperature of

-8\\\\deg C

. Identify the phase diagram which best describes this process.
