insulator is a object that is not a good conductor
So it keeps the heat in.
A ruler is typically made of plastic, which is an insulator. This means it does not conduct electricity well.
An insulator
No, phosphorus is not an insulator. It is a semiconductor, which means it has electrical conductivity in between that of a conductor and an insulator.
Acetate is an insulator. This means it does not conduct electricity very well due to its molecular structure that does not allow electrons to flow easily through it.
Its a insulator
An insulator is a material that does not conduct electricity or heat well. It prevents the flow of electrons or thermal energy, making it suitable for use in electrical insulation or to maintain temperature differences.
A sharpener is typically made of plastic, which is an insulator. This means that it does not conduct electricity well.
Insulator.
A rubber duck is an insulator because it does not conduct electricity. Rubber is a non-conductive material, which means it does not allow electric current to flow through it easily.
An alternative term for thermal insulator is "heat insulator." It refers to a material or device that reduces the transfer of heat energy between two surfaces or objects.
insulator
If you are asking what it is called, it is called an insulator. If you are asking of an example one would be plastic
