Answer 1

If you have an unknown material that conducts electricity and heat well, the most appropriate response would be:

It must be a metal.

Metals are known for their excellent conductivity for both electricity and heat. While some metalloids can conduct electricity better than nonmetals, they typically do not conduct as well as metals. Nonmetals, on the other hand, are generally poor conductors.
