Front

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.

Back
