Which statement is TRUE about kinetic molecular theory?
A) A single particle does not move in a straight line.
B) The size of the particle is large compared to the volume.
C) The collisions of particles with one another are completely elastic.
D) The average kinetic energy of a particle is not proportional to the temperature.

Question

Quizplus · Accepted Answer

The kinetic molecular theory states that gas particles are in constant motion and their collisions with each other and the walls of their container are elastic, meaning there is no net loss or gain of kinetic energy during the collision. A is false as a single particle moves in a straight line unless acted upon by an external force. B is false as the size of the particles is assumed to be negligible compared to the volume they occupy. D is false as the average kinetic energy of a particle is directly proportional to the temperature.
