Detailed explanation-1: -Substances which allow heat to easily pass through them is termed as good conductor and those which do not are termed as bad conductor. Aluminium, copper and gold are few examples of good conductors of heat. Q.

Detailed explanation-2: -Materials that allow electricity to pass through them are called conductors. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.

Detailed explanation-3: -a material that allows heat or electricity to flow through it easily (iron, steel, copper are good conductors). a material that does not allow heat or electricity to flow through it (wood, rubber, plastic are good insulators).

Detailed explanation-4: -A conductor is a material that allows internal (thermal) energy to be transmitted through it easily. Metals, such as copper and aluminium are the best conductors of heat.

Detailed explanation-5: -Conductivity. Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.
