A sealed vessel holds a quantity of oxygen gas at a temperature of 99.7∘C and a pressure of 3.99atm.

50% Part (a) Beginning from the state of the gas as specified in the problem statement, the volume of the vessel is reduced to 51.1 percent of its starting volume while the temperature is held constant. What is the new pressure, in atmospheres, of the oxygen gas? (Assume that the gas approximates an ideal gas.)

50% Part (b) Beginning from the state of the gas at the end of Part (a), the volume of the vessel is reduced to 58.4 percent of that volume while the pressure is held constant. What is the new temperature, in degrees Celsius, of the oxygen gas? (Assume that the gas approximates an ideal gas.)
