Are materials that are good conductors of thermal energy also good conductors of electrical energy?

Final answer:

Good conductors of thermal energy, like silver and copper, are often also good conductors of electrical energy due to the presence of free electrons that help in transporting both electricity and heat.

Step-by-step explanation:

Materials that are good conductors of thermal energy are often also good conductors of electrical energy. This correlation primarily exists because materials like silver, copper, gold, and aluminum have large numbers of free electrons. These free electrons facilitate the conduction of both electricity and heat. Some examples of good thermal conductors are silver and copper, which are also excellent electrical conductors.

On the other hand, good insulators such as wood, plastic, and rubber, which do not conduct heat well, are also poor electrical conductors. The efficiency of thermal and electrical conduction is notably apparent in everyday items such as cooking utensils that are commonly made from metals good at conducting heat.

the answer is yes because all metal are conductors, whereas air pure, water, plastics, glasses, and ceramics are insulators.
