Properties of Gases
| Term | Definition |
|---|---|
| Gas | Substance that has no well defined boundaries but diffuses rapidly to fill any container in which it is placed |
| Boyle's Law | states at a constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure |
| Charles' Law | States at a constant pressure, the volume of a fixed mass of gas is directly proportional to its temperature measured on the kelvin scale |
| Gay lussacs law | In a reaction between gases the volumes of the reacting gases and the volumes of any gaseous products are in the ratio of small whole numbers provided the volumes are measured at the same temperature and pressure |
| Avagadro's law | States that equal volume of gases contain equal numbers of molecules, under the same conditions of temperature and pressure |
| Molar volume | At standard temperature and pressure (S.T.P), one mole of any gas occupy's a volume of 22.4 litres |
| Ideal Gas | Is a gas that obeys all the assumptions of the kinetic theory of gases under all conditions of temperature and pressure |
| Real gases differ from ideal gases | 1) the forces of attraction and repulsion 2) the volume of the molecules is not negligible (except at high pressure) |
| Equation of state for an ideal gas | pV=nRT where T= temperature in kelvin P= Pressure R= Universal Gas constant n= number of moles V= volume |
