Detailed explanation-1: -Q. What materials would be good insulators for a handle on a pan or pot that would be used on the stove? What is the BEST reason cooking pots are made out of the materials aluminum, copper, and sometimes glass? They are able to stop the flow of heat.
Detailed explanation-2: -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. And they are used for cooking, so they are conductors.
Detailed explanation-3: -Fiberglass. Mineral wool and fiberglass are two common types of thermal insulation. Mineral wool is made from steel slag and basalt, making it more eco-friendly than other insulation types.
Detailed explanation-4: -Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
