Is heat conductivity physical property
WebThe heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.It is a measure of a substance’s ability to transfer heat through a material by conduction.Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and gases.
