( Thermal conductivity)
In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier's Law for heat conduction. First, we define heat conduction by the formula where  is the rate of heat flow, k is the thermal conductivity, A is the total cross sectional area of conducting surface, ?T is temperature difference and x is the thickness of conducting surface separating the 2 temperatures. Thus, rearranging the equation gives thermal conductivity,
