1. The table below shows that the thermal conductivity of diamond is significantly higher than that of coinage metals. Given that thermal conduction in metals is primarily driven by conduction electrons, with only a minimal contribution from lattice vibrations, it is intriguing that diamond - an insulator-exhibits much higher thermal conductivity than metals. Explain why the thermal conductivity of diamond is so high.
