| Question | Answer |
|---|---|
| State STP (standard temperature and pressure) | Temperature of 273K (0 °C) and an absolute pressure of exactly 105 Pa |
| Define the kinetic theory of gases | That all matter is made of small particles that are in random motion and that have space between them. |
| State the ideal gas law | PV = nRT (P = pressure, V= volume, n= amount of substance, R=ideal gas constant, T=temperature) |
| Define Boyle's law | That the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. |
| Define Charles law | That the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. |
| Define Gay Lussac's law | That the volumes of gases undergoing a reaction at constant pressure and temperature are in a simple ratio to each other and to that of the product. |
| Define Avogadro's law | That equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. |
