GEOLOGY

Detailed explanation-1: -Aluminum has a high thermal conductivity, so it is a good heat conductor when placed in direct contact with another hot object. However, aluminum can also be used as a reflective insulator because it can reflect radiation from the sun.

Detailed explanation-2: -Materials that do not allow electricity to pass through them are called insulators. Insulators oppose electric current and so they are used as a protection from the dangerous effects of electricity. Examples of insulators are glass, air, wood, plastic and rubber.

Detailed explanation-3: -Bakelite is a a good insulator, and a poor conductor of heat.

Detailed explanation-4: -Pots and pans are not examples of insulators, they are conductors of heat, if it was not so, they could not be used for cooking food.
