nal to the atmospheric pressure. This atmospheric pressure is measured by a barometer . V varied at constant n + T = constant (K 1 ) erefore P and V are inversely proportional 1 = P 2 V 2 T and V are directly proportional. T increases, V increases V/T = constant (K 2 ) Therefore, V = KT V 1 / T 1 = V 2 / T 2 of Constants in Ideal Gas Law atm = 101.3 kPa = 1.013 x 10 5 kg/m(s) 2 .41 L = 0.02241 m 3 mol 3.15 K Molecular Formula November 27, 2007 Quiz : Next Tuesday on everything covered today in lecture Final : cumulative on everything (~60% of final based on chapters 4 and 5) Solid – molecules rigid, don’t move very much; holds shape Liquid – molecules less rigid, move around; does not hold shape, but volume stays constant Gas – molecules move around constantly; does not hold shape or volume Manometers :

Momentum p = mv F = ∆p/ ∆t = m∆v/ ∆t = ma ∆p = m∆v = 2mv To create 14.7 psi, you can tell gas molecules are 1) In constant movement 2) Rapid in their movement 3)
