Calculate the volume occupied by 1.00 mol N2 using the van der Waals equation in the form of a virial expansion at (a) its critical temperature, (b) its Boyle temperature, and (c) its inversion temperature. Assume that the pressure is 10 atm throughout. At what temperature is the gas most perfect? Use the following data: Tc = 126.3 K, a = 1.390 dm6 atm mol^-2, b = 0.0391 dm3 mol^-1
