How might you determine is it a conductor or insulator?

Answer 1

A conductor is when heat can pass through it. An insulator is something that heat does not pass through.

Answer 2

One way to determine if a material is a conductor or insulator is by testing its ability to conduct electricity. Conductor materials allow electricity to flow easily through them, while insulators do not. Another method is to analyze the material's atomic structure; materials with more freely moving electrons tend to be conductors, while materials with tightly bound electrons are insulators.
