Test sub-

stance

Metal/non-

metal

Does the

light bulb

glow?

Conductor

or insulator

Conclusions:

In the substances that were tested, the metals were able to conduct electricity and

the non-metals were not. Metals are good electrical conductors and non-metals are

not.

Thermal Conductors

and Insulators

ESAAI

Athermal conductoris a material that allows energy in the form of heat, to be transferred

within the material, without any movement of the material itself. An easy way to understand

this concept is through a simple demonstration.
