Question

Which material has the highest thermal conductivity?

Answer 1

1. Silver has the highest electrical conductivity of any metal.
2. Silver currently describes conductivity, and all other metals are tested against it.
3. On a scale of $0$ to $100$, gold is rated at $76$, copper is at $97$, and silver is at $100$.
4. Silver is the top conductor since its electrons are more mobile than the other elements, making it the best element for transferring heat and electricity.
