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

The average kinetic energy of a particle is proportional to the temperature in Kelvin.

Explanation:

The kinetic molecular theory states that particles of matter are in constant motion and collide frequently with each other as well as with the walls of the container.

The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.

Therefore, the average kinetic energy of a particle is proportional to the temperature in Kelvin.

yes
