Unformatted text preview: 2. PV = nRT P, V, T are measurable P: pressure (measure with barometer) V: volume of container T: absolute temp. (In Kelvin) n: # of moles of gas R: PV/nT = .0821 L-atm/mol-K o Ideal gas constant o 1 atm = 760mm Hg = 760 torr 3. PV = nRT allows predictions P vs. V P vs. T V vs. T 4. Some mathematical corrections For real gases o Ex. Van der Waals eq. o (P + a [n/V]^2) (V-bn) = nRT o a and b are constants Goals Describe molec. Motion in g, 1, s Compare KEs, speeds of gases Make predictions using PV = nRT...
