Gases P = pressure (a force of the gases on a unit area) Units: atm = 760 mmHg = 760 torr Pascal: Pa (SI unit) / kPa (atm = 101,325 Pa = 101.325 kPa) Psi (lbs/in 2 ) Pressure-volume Relationship (Boyle’s Law) The temperature of a fixed amount of gas at a constant temperature is inversely proportional to the volume of the gas PV = nRt (R is constant) R = PV/nt = 0.08206 atm·L / mol·k P 1 V 1 = P 2 V 2 Temperature-volume Relationship (Charles’ Law) V 1 /T 1 = V 2 /T 2 (Kelvin Temperature) Standard temperature and pressure 273 K 1 atm 1 mol = 22.4 L Molar Mass Gas Equation MM = m/n d = m/V PV = (m/MM) Rt MM = dRt/P Dalton’s Law of Partial Pressure The total pressure of a gaseous mixture equals the sum of the partial pressures of each gas in the mixture
