A. remain the same
B. not enough information to answer the question
C. increase
D. decrease
2. A 1.18 mol sample of CO2 gas is confined in a 27.8 liter container at 14.5 �C.

3.A 0.855 mol sample of Xe gas is confined in a 20.5 liter container at 19.6 �C.
If the volume of the gas sample is decreased to 10.3 L, holding the temperature constant, the pressure will increase. Which of the following kinetic theory ideas apply?
Choose all that apply.
A. With less available volume, the molecules hit the walls of the container more often.
B. At lower volumes molecules have higher average speeds.
C. With higher average speeds, on average the molecules hit the walls of the container with more force.
D. For a given gas at constant temperature, the force per collision is constant. Some other factor must cause the pressure increase.
E. None of the Above
