5.9: Mean Free Path, Diffusion, and Effusion of Gases

(a) Given a mean free path λ=0.4  nm and a mean speed ⟨v⟩=1.17 ×10^5  m / s for the current flow in copper at a temperature of 300 K , calculate the classical value for the resistivity ρof copper. (b) The classical model suggests that the mean free path is temperature independent and that ⟨v⟩depends on temperature. From this model, what would ρbe at 100 K ? | Numerade
