Gases in Motion: Kinetic Theory

Postulates of the Kinetic Theory

3 pts

volume_mute

particles in constant, random motion, colliding elastically

Select every statement that is part of the kinetic theory of gases.

Each collision causes the gas to steadily lose energy.

There are no attractive or repulsive forces between gas particles.

Gas particles are packed tightly together and nearly touching.

Collisions between gas particles are elastic (no net loss of energy).

Gas particles are in constant, random motion.

Gas particles are separated by distances large compared to their own size.
