Answer:

1. Copper, Yes

2. Materials that are good conductors of heat and electricity must-have free electrons that can carry the energy from one compound to the next.

3. Rubber

Explanation:

Explainations for the following numbers~

1. Yes. Conduction of electricity requires the presence of free charge carriers. However, heat can be conducted via free electrons OR through vibrational diffusion through a solid material.

2. Usually good current carrying conductors should have following properties: Low resistivity/ / high conductivity. Low temperature coefficient of resistivity. Good thermal conductivity.

3. The space between the molecules makes it a very bad insulator. Its electrons are locally bound and not free as is the case with metals. radiation, conduction, or convection.
