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 principle of kinetic molecular theory is that gases are made up of tiny particles that have constant random motion. The collisions of particles with one another is completely elastic, meaning that there is no loss of energy or momentum during the collisions. A) is false because a single particle does move in a straight line unless it collides with another particle. B) is false because the size of the particle is negligible compared to the volume of the container. D) is false because the average kinetic energy of a particle is directly proportional to the temperature.
