This is the six point model that is used to explain the behavior of gases

1. Gases are composed of atoms or molecules that have mass 2. Gases are in constant, random, straight line motion 3. The particles that make up a sample of a gas are separated from each other by great distances This is why the volume is NOT FIXED 1. Gases are composed of atoms or molecules that have mass 2.

4. Gas particles collide with each other and the container that they are in All of these collisions result in a transfer of energy from particle to particle Or from particle to surroundings No energy is ever lost completely and these are called ELASTIC COLLISIONS. 4.

5. Gas particles have no attraction for each other 6. Gases are highly sensitive to changes in temperature and pressure 5. Gas particles have no attraction for each other 6. Gases are highly sensitive to changes in temperature and pressure

Ideal gases follow all of the rules for gas behavior Hydrogen and Helium are the two most ideal gases that exist Real Gases do not always follow each of the six points of KMT.

1. Sometimes the particles in a mixture of gases are attracted to each other because of differences between elements This is especially true during temperature or pressure changes 1.

As the pressure that is on a sample of a gas increases we begin to confine the gas to a smaller space Once trapped in a smaller space, gases will have a volume that we can measure As the pressure that is on a sample of a gas increases we begin to confine the gas to a smaller space Once trapped in a smaller space, gases will have a volume that we can measure

Gases are most ideal when we have: HIGH TEMPERATURE AND LOW PRESSURE Under these conditions they follow the points of KMT the best. So……400 K and 0.1 atm is good But…...3 K and 100 atm is NOT GOOD So Low Temperature and High pressure is when they are least ideal.
