KMT Postulates

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

According to the kinetic molecular theory, the volume actually occupied by the molecules of a gas is negligibly small; the vast majority of the volume of the gas is empty space through which the gas molecules are moving.

• True

• False
