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

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

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

Which of the following is NOT a part of the Kinetic Theory of Matter?

• All matter is made up of tiny particles.
• Occasionally, particles stop moving.
• Particles are always moving in random paths.
• The type of movement of particles depends on the amount of energy.
