Thermal conductivity

(a) Copper has an electrical conductivity of 5.96 × 107 S/m. Estimate the thermal conductivity of copper.

(b) At 25°C, diamond has a high thermal conductivity of 23.5 W cm-1 K-1 and a high electrical resistivity of ρ = 1016 Ω cm. Can these properties be explained by the Wiedemann-Franz law? Why or why not?
