Prediction of thermal conductivities of gases at tow density, 

(a) Compute the thermal conductivity of argon at 100°C and atmospheric pressure, using the Chapman-Enskog theory and the Lennard-Jones constants derived from viscosity data. Compare your result with the observed value of 506 x 10^-7 cal/cm ∙ s ∙ K. 

(b) Compute the thermal conductivities of NO and CH₄ at 300K and atmospheric pressure from the following data for these conditions: Compare your results with the experimental values given in Table 8.-1-1.
