thermal conductivity

Noun

 * 1)  A measure of the ability of a material to conduct heat, often denoted k, λ, or κ.

Usage notes
The heat (thermal energy) flow Pth through a plate made of a given material depends on the thermal conductivity λ of that material, the surface of the plate A, the temperature difference over the plate ΔT and the thickness of the plate d, and follows the formula:


 * $$P{_t}{_h} = \lambda \ \frac{A \times \Delta T}{d}$$

Thus, the higher the conductivity, the higher the heat flow. The unit of thermal conductivity in SI system of units is W·m-1·K-1.
