Additional Information :

• All solids do not conduct heat in the same manner depending on the ability to conduct heat substances are classified as conductors and insulators.

• Insulators are substances which do not conduct heat or conduct heat poorly.

• Plastic and wood are poor conductors of heat and thus used to make handles for cooking vessels or to make laddles to serve.

• Stone, glass , air , fur and paper are all insulators.

• Furs of animals such as Polar Bears and seals living in the cold Arctic region trap the air and create an excellent insulating layer around the body.

• This allows animal to keep its body warm at low temperatures.

• Substances through which heat passes are called conductors. Most metals are good conductors of heat.
