The Wiedemann-Franz Law states that good conductors of electricity are also good conductors of heat. Vanadium dioxide not only switches from an insulator to a conductor at 67C (152F), but it appea ...

There are better heat conductors but they aren't practical materials for producing computer heatsinks: silver exceeds copper's thermal conductivity at 429W/mK (hence Arctic Silver thermal paste ...

So, conduction in metals is faster than in non-metals. Metals are good conductors of heat energy because they contain free electrons. Cooking pans are made of metal. Energy is transferred to the ...
