What is a poor conductor of electricity?
Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies. Cables are wires covered in plastic so we can handle them safely.

What are good conductors of heat give examples?
– Metal is a good heat conductor because it lets heat flow through it easily. – Copper and silver are the best heat conductors. – Copper conducts heat ten times better than iron. – When heat travels by conduction through a heat conductor, the heat is passed on from one atom to the next. The heat flows, the heated atoms don’t!
