Print out one of these pictures and explain what is happening in terms of kinetic molecular theory and pressure. |
 |
| As nitrogen gas is heated, molecules gain kinetic energy (that is, they speed up) Each molecule has its own velocity, but the proportion of molecules which are going faster increases. The blue line represents the colder, slower atoms.Their speeds are more similar than the hotter, faster molecules. |
 |
| This is a picture of a closed end manometer. You can see that the gas, A, is pushing harder than the gas, B. This means that A has higher pressure than B. |
 |
| In the manometer above, B would be one of the gases on the left side of this picture, it has less molecules pushing against the mercury. "A" would be one of the gases to the right of "B" because each molecule increases the forces pushing the masses upwards. |
