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