GEOLOGY

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.

Detailed explanation-2: -Conductors allow heat to pass through them through vibration of the molecules.

Detailed explanation-3: -A conductor conducts electricity since it offers little or no resistance to the flow of electrons, thus leading to a flow of electrical current. Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors.

Detailed explanation-4: -An insulator is a material that does not allow a transfer of electricity or heat energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Feather, fur, and natural fibers are all examples of natural insulators.
