Is glass a thermal insulator or conductor?

Likewise, is glass a conductor or insulator?

An insulator is a material that does notconductheat or electricity. In comparison, conductors arethematerials that conduct electricity and/or heat. Aluminum is agoodconductor of heat and electricity. Glass, ontheother hand, is an insulator and so isrubber.

Similarly, why is glass a bad conductor of heat? Glass is a very poor heat conductor. Ithasone of the lowest possible heat conduction a solid(withoutair trapped in it) can possibly have, this is mostly dueto its lackof ordered crystal structure. Since it's an insulator,theelectronic contribution to the thermal conductivity isverysmall.

Correspondingly, why is glass a good insulator?

Glass is used as an insulator becauseithas atoms that have electrons that are closely connected witheachother. And because of this property, it does not allowelectrons tofreely roam around and be shared by nearby atoms thuspreventingthe flow of electrical current in othermaterials.

Is glass or metal a better conductor of heat?

Copper is a better heat conductorthanglass. In general, we think of metals asgoodconductors. In fact, metals vary widely intheirconductivity but, overall, they are better conductorsofheat than most liquids and gasses. Wood is an example ofasolid that is a poor heat conductor.
