| Ideal Gas Law | to determine P, V, T or number of moles for a static condtion |
| Pressure | a measure of the frequency of gas molecules hitting the walls of the container (in atm) |
| Volume | a measure of the amount of space an object takes up |
| Temperature | a measure of the average kinetic energy of a substance |
