1. Ideal Gases (5.4)

2. Kinetic Energy is great than Attractive Forces…gas molecules move freely and randomly in all directions

3. Gas molecule movement & Temperature

4. Elastic Collisions NO net loss of KE (This is like gas with gas molecule)

5. Elastic Collisions NO net loss of KE (This is like gas with container wall… notice that the velocities are the same.)

6. Gases take shape of their containers

7. Heavier gases may have lower KE initially, once they get going, the may have the same KE as lighter gases… see how all lines eventually reach the same speed at that temperature.
