Question

In Fourier&#39;s law, the proportionality constant is called the-A-heat transfer co efficientB-thermal diffusivityC-thermal conductivityD-Stefan Boltzman constant-C-thermal conductivity

APTITUDE CRACK · Accepted Answer

The correct option is  C thermal conductivity In Fourier&#39;s law of heat conduction, the proportionality constant is called the thermal conductivity (&#119896;k). Fourier&#39;s law states that the rate of heat transfer (&#119876;Q) through a material is directly proportional to the temperature gradient (&#119889;&#119879;/&#119889;&#119909;dT/dx) across the material, and is given by: &#119876;=&minus;&#119896;&#119889;&#119879;&#119889;&#119909;Q=&minus;kdxdT​ Where: &#119876;Q is the rate of heat transfer (W), &#119896;k is the thermal conductivity of the material (W/m&middot;K), &#119889;&#119879;dT is the temperature difference (K), and &#119889;&#119909;dx is the distance over which the temperature gradient occurs (m). Therefore, the correct term for the proportionality constant in Fourier&#39;s law is: thermal conductivity.
