Question

What do you understand by 'thermal coductivity'? What is a poor conductor of heat?

Answer 1

Thermal conductivity is the ability of any object to conduct or allow heat to pass through it. It is one of the properties of metals which differentiates them from non metals. a substance that does not allow heat to pass through it are called insulators or poor conductors of heat. Except graphite, all non metals are generally poor conductor of heat, and exhibit low thermal conductivity.
