Question

Why is a good conductor of electricity also a good conductor of heat? 1. For both electricity and heat, the conduction is via electrons, which in a metal are loosely bound, easy ?owing, and easy to start moving. 2. Bound electrons do not exist in materials that are good conductors for both heat and electricity. 3. For both electricity and heat, the conduction is via atoms, which in a metal are loosely bound, easy ?owing, and easy to start moving. 4. They all carry energies for both electricity and heat. 5. If there is a current through a conductor, there should also be heat produced by resistance.

Explanation / Answer

For both electricity and heat, the con- duction is via electrons, which in a metal are loosely bound, easy ?owing, and easy to start moving. correct Electrons in a metal are loosely bound, ?ow easily, and easy to get moving; an important requirement for heat and electricity.
