conduction transfer of heat or electricity through a substance, resulting from a difference in temperature between different parts of the substance, in the case of heat, or from a difference in electric potential, in the case of electricity.
In solids, electric current consists of a flow of electrons; as in the case of heatconduction, metals are better conductors of electricity because of their greater free-electron density, while nonmetals, such as rubber, are poor conductors and may be used as electrical insulators, or dielectrics.

Gradient heat transport depends on three quantities: the conductivity of the material, the cross-sectional area of the material, and the spatial gradient of temperature.
The larger the conductivity, gradient,and/or cross-section, the faster the heat flows.
In this experiment, the flow of heat through a collection of conductive bars which vary in cross-section is simulated.
