GEOLOGY

Detailed explanation-1: -Copper, silver, aluminum, gold, steel, and brass are common conductors of electricity.

Detailed explanation-2: -In insulating materials, the outer electrons are not so free to move. All metals are electrically conductive.

Detailed explanation-3: -Thus, all metals are conductors, whereas air, (pure) water, plastics, glasses, and ceramics are insulators.

Detailed explanation-4: -Examples of Conductors Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity. We use them in electric circuits and systems in the form of wires. Mercury is an excellent liquid conductor. Thus, this material finds use in many instruments.

Detailed explanation-5: -Metal is a good conductor of heat, while wood and plastic are good insulators. A conductor transfers thermal energy (heat) well, while an insulator does not transfer thermal energy (heat) well.
