A 1.24 mol sample of O2 gas is confined in a 29.8 liter container at 19.4 °C. If the temperature of the gas sample is decreased to -4.10 °C, holding the volume constant, the pressure will decrease because: Choose all that apply. With lower average speeds, on average the molecules hit the walls of the container with less force. At lower temperatures molecules have lower average speeds. With higher average speeds, the molecules hit the walls of the container more often. As the number of molecule-wall collisions increases, the force per collision decreases. None of the Above

A 1.64 mol sample of CO2 gas is confined in a 39.6-liter container at 21.6 °C. If the volume of the gas sample is decreased to 19.8 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. For a given gas at constant temperature, the force per collision is constant. Some other factor must cause the pressure increase. At lower volumes molecules have higher average speeds. With less available volume, the molecules hit the walls of the container more often. None of the Above

A 0.826 mol sample of O2 gas is confined in a 19.4 liter container at 13.6 oC. If the temperature of the gas sample is increased to 35.3 oC, holding the volume constant, the pressure will increase because: Choose all that apply. A. At higher temperatures molecules have higher average speeds. B. As the average speed increases, the number of molecule-wall collisions decreases. C. With lower average speeds, the molecules hit the walls of the container less often. D. With higher average speeds, on average the molecules hit the walls of the container with more force. E.
