Thermal conductivity - Simple English Wikipedia, the free ...

Thermal conductivity is the ability of a material to conduct heat. Metals are good at heat conduction. They are good conductors of heat. Gasses are also good conductors of heat. Thermal resistivity is the opposite of thermal conductivity. This means not conducting heat much.

Thermal conductivity - Wikipedia

Thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat.It is evaluated primarily in terms of 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.
