Problem 37

Some vapor pressure data for Freon-12, once a common refrigerant, are 2.0 atm; 5.0 atm; 42.4 10.0 atm; 20.0 atm. Also, Use these data to plot the vapor pressure curve of Freon-12. What approximate pressure would be required in the compressor of a refrigeration system to convert Freon- 12 vapor to liquid at ?
