Which material allows heat and electricity to pass through easily?

• A. Conductor
• B. Insulator
• C. Natural Resource
• D. Man-made Resource

Answer: (A)

Materials that let heat and electricity pass through easily are called conductors. This happens because they have free-moving electrons that carry energy quickly from place to place. In the question, the material that fits this description is a conductor. Metals like copper and aluminum are classic examples and are used in wires because energy moves through them readily. An insulator, by contrast, resists the flow of energy, so heat or electricity don’t move through easily—think plastic handles or wooden spoons. The terms natural resource or man-made resource describe where something comes from, not how well it conducts energy, so they don’t answer the question.
