A poor conductor of heat is any material that can not transfer heat. Poor conductors have a low density thus the particles in a given volume of the material are not enough to collide and transfer heat. Examples of poor heat conductors include air, wood, paper, cloth and water. All gases and liquids are poor conductors of heat.

What is heat conduction? - Phys.org

In other words, the metal conducts heat well, but the plastic does not. Conclusion. Metal is a good thermal conductor, while plastic is a poor thermal conductor. An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being good thermal insulators.

thermodynamics - Why is air a poor conductor of heat ...

Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects. Heat can only travel from a hot material to a cold material.

Why is water a poor conductor of heat? - Quora

Good and bad conductors of Heat. Thermal conductivity of a substance is the ability of that substance to conduct heat. A measure of the “goodness” or the ”badness” of a substance for the flow of heat through conduction is provided by its thermal conductivity.
