Thermal conductivity - Wikipedia

2018-9-1Thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat.It is evaluated primarily in terms of the Fourier''s Law for heat conduction.In general, thermal conductivity is a tensor property, expressing the anisotropy of the property.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.
