A 0.558 mol sample of N2 gas is confined in a 14.3 liter container at 39.4 °C. If the volume of the gas sample is decreased to 7.15 L, holding the temperature constant, the pressure will increase. Which of the following kinetic theory ideas apply? Choose all that apply. With higher average speeds, on average the molecules hit the walls of the container with more force. With less available volume, the molecules hit the walls of the container more often. At lower volumes molecules have higher average speeds. For a given gas at constant temperature, the force per collision is constant. Some other factor must cause the pressure increase. None of the Above
