| Kinetic Molecular Theory | Explains the states of matter based on the concept that the particles in all forms of matter are in constant motion. |
| Pressure | Force exerted by particles per unit surface area |
| Pascal | SI Unit of pressure |
| Elastic collision | collision where no kinetic energy is lost or transferred |
| Diffusion | tendency of molecules to move from an area of greater to lower concentration. |
| Effusion | Process that occurs when a gas escapes through a tiny hole in its container. |
| Temperature | A measure of the average kinetic energy of particles in a substance. |
| Boyle's Law | States that for a given mass of a gas at constant temperature, the volume of the gas varies inversely with the pressure. |
| Charles's Law | States that the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. |
| Gay-Lussac's Law | States that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant |
| Combined Gas Law | A single expression that combines the three gas laws. |
| Ideal Gas Law | Permits you to calculate the number of moles of a contained gas when the pressure, temperature and volume are known |
| Avogadro's Law | States that equal volumes of gases at the same temperature and pressure contain equal numbers of particles. |
| Partial Pressure | The contribution each gas in a mixture makes to the total pressure. |
| Kinetic Energy | The energy an object has because of its motion. |
