Refrigerant R-134a with a mass of 0.08 kg is expanded adiabatically from a superheated vapor at 10 bar, 40 C to a saturated liquid-vapor mixture at 1 bar producing 3 kJ of work output. Determine the final temperature and the change in volume for the process. Sketch the process on a p-v diagram. Neglect changes in kineticand potential energy.
