Computer Science 106: MATLAB HW 2, due 2/5 Build a table The ideal gas law is pV = nRT R = 8.31446 J/mol K for pressure in Pascals, volume in cubic meters, T Kelvin, n moles. (1 atm = 101325 Pa = 101.325 Bar, 1 Pa = 1 N/m 2 ) (try the calculation for standard temperature and pressure: 101325 Pa (1 atm) and 273 K for 1 mole and find that the volume is .0224 m 3 or 22.4 liters) If one takes into account, the finite size of molecules instead of treating molecules as points, and the van der Waals attraction between neutral molecules, one derives the van der Waals gas equation: (p+ a n 2 /V 2 ) (V‐ nb) = nRT You can find tables of van der Walls constants for a number of small molecules at http://en.wikipedia.org/wiki/Van_der_Waals_constants_%28data_page%29 These constants, a and b assume units of liters, bar = 100 000 Pa (a bit less than 1 atm), K and moles; R is 8.31446 x 10 ‐2 in these units. Solve the van der Waals and ideal gas equations for p. For both, compute p for n = 1
