| KINETIC MOLECULAR THEORY OF GASES |
|
Definition
* gases move in constant random straight line motion
* gases do not lose or gain energy when they collide -- they have elastic collisions
*gas particles have a volume that is insignificant compared to the volume of the total gas
* average kinetic energy is temperature
* gas particles have no significant forces between them |
