WebDiffusion in dilute gases is in some ways more complex, or at least more subtle, than either viscosity or thermal conductivity. First, a mixture is necessarily involved, inasmuch as a gas diffusing through itself makes no sense physically unless the molecules are in some way distinguishable from one another. Second, diffusion measurements are rather … WebLet us estimate the viscosity of a gas mixture consisting of 20% Zn vapor, 50% N2, and 30% CO at 1000 oC. The density of zinc at its melting point (Tm=692 K) is approximately 7.14 g cm-3. Therefore, its molar volume at that temperature is calculated to be = 65.38/7.14 = 9.16 cm3/mole and the corresponding σ c=2.55 Å (see (3.2.3)).
