Materials such as rubber, glass, and wood are good insulators because they have high resistance to the flow of electricity and heat. These materials inhibit the transfer of energy, making them effective at maintaining temperature differences and preventing electrical currents from flowing.
Yes, ceramic is an insulator material.
No, a material cannot be both a non-conductor and a non-insulator. A non-conductor is a material that does not allow the flow of electric current, while an insulator is a material that minimizes the flow of electric current. If a material is not conducting electricity, it is considered an insulator.
Vacuum is a better insulator than fiberglass. Vacuum has no particles to transfer heat through, while fiberglass relies on slowing down heat transfer through its material. This makes vacuum a more effective insulator, as it minimizes heat transfer through conduction and convection.
Black cloth is not necessarily an insulator on its own. The insulating properties of a material depend on its composition and thickness. In general, thicker and denser materials provide better insulation.
Glass is a better insulator than plywood when the same thickness of material is used. This is because glass has lower thermal conductivity than plywood, meaning it can restrict the flow of heat better. You can determine this by looking up the thermal conductivity values of plywood and glass and comparing them.
No. A higher R-value is a better insulator.

any material that does not conduct electricity is an insulator.

Yes but it depends on the type of material.

One material that conducts thermal energy poorly is Styrofoam. This material has a low thermal conductivity due to its high concentration of trapped air pockets, which hinders the transfer of heat. This property makes Styrofoam a good insulator for keeping things cool or warm.
