| absolute zero | temperature at which a gas theoretically occupies zero volume. |
| universal gas constant | 0.08206 (L*atm)/(mol*K) |
| Boyle's law | at constant temperature, the volume of a given amount of gas is inversely proportional to its pressure. |
| Charles's law | at constant pressure, the volume of a given amount of gas is directly proportional to its kelvin temperature. |
| Avogadro's law | at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas. |
| combined gas law | (P1*V1)/T1 = (P2*V2)/T2 |
| Dalton's law of partial pressures | the total pressure of a mixture of gases is the sum of the pressures that each gas would exert if alone in the container. |
| molar volume of ideal gas at STP | 22.4 liters |
