A rigid tank initially contains 100 L of saturated liquid and 100 L of saturated vapor of R-12 at 0 °C. A relief valve at the top of the tank allows R-12 vapor to escape when the pressure inside the tank reaches 745 kPa, so that the pressure inside the tank never exceeds that value. The valve at the bottom of the tank is opened, allowing 10 kg of R- 12 from the pipe (10 °C and 900 kPa) to enter the tank. During the process, a total of 11.5 MJ of heat are transferred to the tank. Determine the final mass and final conditions of R-12 at the end of this process.
