20.A 0.973 mol sample of CO2 gas is confined in a 23.6 liter container at 22.5 °C. If the volume of the gas sample is decreased to 11.8 L, holding the temperature constant, the pressure will increase. Which of the following kinetic theory ideas apply?

Choose all that apply.

*For a given gas at constant temperature, the force per collision is constant. Some other factor must cause the pressure increase.
*With less available volume, the molecules hit the walls of the container more often.
*At lower volumes molecules have higher average speeds.
*With higher average speeds, on average the molecules hit the walls of the container with more force.
*None of the Above
