Kinetic Theory of Gases

The kinetic molecular theory of gases allows us to understand the behavior of gases. The kinetic molecular theory of gases describes five physical properties of gases:

1. Gases are comprised of a large number of molecules that are in constant, random motion
2. The volume of a gas particle is negligible when compared to the total gas volume
3. The gas particles exert no attractive or repulsive forces between them
4. No energy is lost in the collisions between the particles of a gas; although one gas particle may gain energy at the expense of another, energy is conserved in these "elastic" collisions
5. The average kinetic energy of the gas particles is proportional to the absolute temperature of the gas
