| point mass | an ideal gas praticle with mass, but no dimensions |
| ideal gas | a model in which gas particles are mass points and exert no attraction for each other |
| standard atmospheric pressure | 101.325 kPa |
| standard temperature | thermodynamic reference conditions, 25°C, 100kPa |
| STP | standard temperature and atmospheric pressure |
| Boyle's Law | the volume of a specific amount of gas varies inversely as the pressure if the temperature remains constant |
| Dalton's Law | in a mixture of gases, the total pressure of the mixture is the sum of the partial pressures of each component gas |
| Charles's Law | the volume of a specific amount of gas varies directly as the absolute temperature if the pressure remains constant |
| Diffusion | the spontaneous spreading of particles throughout a given volume until they are uniformly distributed |
| Graham's Law | the ratio of the relative rates of diffusion of gases is equal to the square root of the inverse ratio of the molecular masses |
| real gas | a gas with particles of finite volume and van der Waals forces between particles |
| adiabatic system | system in which heat neither leaves nor enters |
| Avogadro's principle | equal volumes of gases at the same temperature and pressure contain the same number of molecules |
| molar volume | the volume occupied by one mole of a substance; equal to 22.414 dm^3 for a gas at standar temperature and standard atmospheric pressure |
| ideal gas equation | PV=nRT |
| limiting reactant | the reactant that is consumed completely in a chemical reaction |
| excess reactant | reactant remaining when all of some other reactant has been consumed |
