An engineer is modeling the behavior of nitrogen gas in a high-pressure cylinder using the kinetic theory of ideal gases. Which of the following assumptions of the kinetic molecular model is not correct?
The total volume of the nitrogen molecules themselves is negligible compared to the volume of the cylinder.
The attractive electrostatic forces between nitrogen molecules are negligible except during collisions.
The duration of any collision between a nitrogen molecule and the cylinder wall is negligible compared to the time between collisions.
The average distance a nitrogen molecule travels between collisions is much smaller than the molecular diameter.
