The Ideal Gas Law

Q. The vapor pressure of liquid carbon tetrachloride, CCl4, is 40.0 mm Hg at 277 K. A sample of CCl4 is placed in a closed, evacuated container of constant volume at a temperature of 446 K. It is found that all of the CCl4 is in the vapor phase and that the pressure is 52.0 mm Hg. If the temperature in the container is reduced to 277 K, which of the following statements are correct?
