Why are good electrical conductors also good thermal conductors?
Is there any material that is a good electrical conductor but not a good thermal conductor?
Yes, there are some materials like that. For example, bismuth is a good electrical conductor but not a good thermal conductor. This is because its electrons are not as free to move around as those in other metals like copper or aluminum. As a result, bismuth is not able to conduct the same amount of heat energy as those other metals, even though it can conduct electricity just as well.
