Question

enterprise that require knowledge of tgermal conductivity of different metals

Answer 1

Answer:

The defining equation for thermal conductivity is {\displaystyle \mathbf {q} =-k\nabla T}, where {\displaystyle \mathbf {q} } is the heat flux, {\displaystyle k} is the thermal conductivity, and {\displaystyle \nabla T} is the temperature gradient. This is known as Fourier's Law for heat conduction. Although commonly expressed as a scalar, the most general form of thermal conductivity is a second-rank tensor. However, the tensorial description only becomes necessary in materials which are anisotropic.
