# Problem: Which postulate of the kinetic molecular theory breaks down under conditions of high pressure? Explain.a) The average kinetic energy of a particle is proportional to the temperature in kelvins. b) The size of a particle is negligibly small. c) The collision of one particle with another (or with the walls) is completely elastic.

3 postulates of the Kinetic Molecular Theory:

1) Volume of real gases are negligible and small.

2) The average kinetic energy of gases are directly proportional to the absolute temperature in Kelvin.

3) Collisions between ideal gases are completely elastic.
