Thermal conductivity of common metals, metallic elements aand Alloys

Thermal Conductivity - k - is the quantity of heat transmitted due to an unit temperature gradient, in unit time under steady conditions in a direction normal to a surface of the unit area. Thermal Conductivity - k - is used in the Fourier's equation.

A noninsulated uniform rod positioned between two walls of constant but different temperature. The finite-difference representation employs four interior nodes. Where T =temperature ( C), x =distance along the rod (m), h′ =a heat transfer coefficient between the rod and the surrounding air (m−2), and T a = the air temperature ( C). Since one iron rod is twice the diameter of the other, it has four times the cross-sectional area, and thus should conduct heat four times as fast. It also has, however, four times the mass of the other rod, and so requires four times as much heat to raise its temperature by the same amount.

If one end of a metal rod is at a higher temperature, then energy will be transferred down the rod toward the colder end because the higher speed particles will collide with the slower ones with a net transfer of energy to the slower ones.
