A mass of 10 kg of saturated liquid-vapor mixture of R-12 is contained in a piston-cylinder device at 0oC. Initially half of the mixture is in the liquid phase. Heat is now transferred, and the piston, which is resting on a stop-ring, starts moving when the pressure reaches 500 kPa. Heat transfer continues until the total volume doubles. Determine.
(a) The final pressure.
(b) Work.
(c) Heat transfer in the entire process. Also, show the process on a p-v diagram.
