front 1 Avogadro's Law | back 1 equal volumes of gases at the same temperature and pressure contain equal numbers of particles |
front 2 Boyle's Law | back 2 for a given mass of a gas at constant temperature, the volume of the gas varies inversely with pressure |
front 3 Charles' Law | back 3 the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant |
front 4 Combined Gas Law | back 4 the law that describes the relationship among the pressure, temperature, and volume of an enclosed gas |
front 5 Dalton's Law of Partial Pressures | back 5 at constant volume and temperature, the total pressure exerted by a mixture of aases is equal to the sum of the partial pressures of the component gases |
front 6 Gay-Lussac's Law | back 6 the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constan |
front 7 Ideal Gas Constant | back 7 the constant in the ideal gas law with the symbol R and the value R 8.31 L kPa mol' K |
front 8 Ideal Gas Law | back 8 the relationship PV = RT, which describes the behavior of an ideal gas |
front 9 kinetic molecular theory | back 9 model that explains the physical properties of gases based on the submicroscopic behavior of gas particles; in mathematical form, it yields the ideal gas equation |
