Document Summary

Gas laws: gas laws, boyle"s law - the volume of a xed quantity of gas at constant temperature is inversely proportional to the pressure. P1v1 = p2v2: charles"s law - the volume of a xed amount of gas at constant pressure is directly proportional to its absolute temperature, v = constant x t. T2: gay-lussac"s law - at a given temperature and pressure, the volumes of gases that react with each other is in a ratio of small whole numbers (stoichiometry based!, relates temperature and pressure at constant volume. In a rigid walled container, volume is constant. Pressure is directly proportional to the absolute temperature " T2: avagadro"s law - the volume of a gas at constant temperature and pressure is directly proportional to the number of moles of the gas " V n: so, at stp, one mole of any gas occupies 22. 4 l, v = constant x n a) Ideal gas law: pv = nrt a)
