Answer
Answer
- Copper metal is used for making electric wires because it is highly ductile in It is a good conductor of electricity.
- Graphite is made of Its valence electrons are free to move. As a result, graphite is able to conduct electricity which makes it useful for making an electrode in a cell.
Immersion rods for heating liquids are made of metallic substances because metallic substances are good conductors of electricity and heat.
