Q:

Is air a good conductor of heat?

Full Answer

Conduction is the transfer of heat through physical contact with a material, and air does not allow for this type of transfer. Instead, air helps keep heat in, and therefore is a key component in many types of insulation.

Materials such as wood, paper and cloth are also poor conductors of heat. Excellent conductors of heat include metals and stone, as they can quickly transfer warmth.
