WebConductors allow charge to pass freely through them, whereas insulators do not. Obviously, string is an insulator, and copper is a conductor. As a general rule, substances which are good conductors of heat are also good conductors of electricity. Thus, all metals are conductors, whereas air, (pure) water, plastics, glasses, and ceramics are ... WebMetals have been used to manufacture cookware because of their ability to conduct heat. Since metals are also good conductors of electricity they are widely used in the production of electrical appliances. In this experiment students will learn how different metals conduct heat. Materials: Aluminum, copper, & stainless steel cookware – all ... WebAre all metals good conductors of heat and electricity? Obviously, string is an insulator, and copper is a conductor.
