Kinetic Theory Gases

 

The kinetic theory of gases explains the behavior of gases in a container.  The best way to understand this by imagining pool balls on a pool table. If the pool balls were to be completely elastic the pool balls would not loose any energy when they collide with each other or the side rails. This would mean that they would never stop. The more energy you put into the pool balls the faster they would go and the greater the number of collisions would happen. As energy continues to increase the pool balls collide with each other and the side rails with a greater force.  Eventually the collisions become so great that the side rails would either explode or expand to reduce the number of collisions. The same is true with gases in a container. The container acts the side rails on the pool table and the pool balls as the molecules in the container.
