thermal conductivity

== English == === Noun === thermal conductivity (plural thermal conductivities) (physics) 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 = λ A × Δ T d {\displaystyle 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. ==== Synonyms ==== heat conductivity ==== Related terms ==== thermal conductance ==== Translations ====
