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 is 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 the collisions between particles are completely elastic, meaning that there is no loss of kinetic energy during collisions. This allows for the transfer of kinetic energy between particles and the conversion of energy from kinetic to potential and back again. Choices A, B, and D are all false. A single particle in the gas phase moves in a straight line until it collides with another particle or a container wall. The size of gas particles is negligible compared to the volume they occupy. And the average kinetic energy of a particle is directly proportional to the temperature.
