Kinetic Molecular Theory A Model for Gases

In prior chapters we have seen the importance of models or theories in imder-standing nature. A simple model for understanding the behavior of gases is the kinetic molecular theory. This model predicts the correct behavior for most gases imder many conditions. Like other models, the kinetic molecular theory is not 

No attractions or repulsions between particles collisions like billiard ball collisions 

A lot of space between the particles compared to the size of the particles themselves 

The speed of the particles increases with increasing temperature 

A gas is a collection of particles (molecules or atoms) in constant, straight-line motion.
