Gases and KMT

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 one of the assumptions of the kinetic molecular theory for ideal gases?

• The particles attract and then repel each other.

• The collisions between particles are elastic

• The particles are in constant random motion.

• The particle size is very small compared to the space between the particles.
