Final answer:
An example of a conductor, which allows electrical and thermal energy to move through it easily, is a metal such as copper.
Step-by-step explanation:
In the context of identifying materials based on their conductivity, an example of a conductor is typically a metal such as copper. Conductors are materials that allow charge to move through them relatively easily, which makes them essential in various applications such as electrical wiring and circuitry. Metals are not only good electrical conductors but also efficient thermal conductors, meaning they can conduct heat well. On the contrary, materials like rubber, glass, and wool fabric are considered insulators because they do not allow electrons to move freely, making them useful in preventing the unwanted transfer of electricity or heat.
