It depends on whether it's referring to heat or electricity. For heat, it means that it is good at preventing heat transfer from one area to another, for electricity it means it's highly resistant to electrical conductivity.

What does Good electrical insulator mean?

An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.

A material that conducts thermal energy poorly?

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.


Why is foam a good insulator?

It is made if non conducting material and its structure traps air which is an excellent insulator in its own right


What does it mean if a material a good Heat Insulator?

If a material is a good heat insulator, it has low thermal conductivity, meaning it does not easily allow heat to pass through it. This property helps to maintain temperatures by preventing heat transfer between different areas or objects. Materials like wool, fiberglass, and foam are examples of good heat insulators.


Is a wooden stick a conductor or insulator?

A wooden stick is an insulator because wood does not conduct electricity well due to the lack of free electrons that can move easily through the material. It is not a good material for transmitting electrical current.


What material has a poor energy conductor?

Wood is a material that has poor energy conductivity, making it a good insulator. This is why wooden utensils are commonly used in cooking to prevent burns from hot surfaces.
