Thermal Conductivity**
The ability of a material to conduct heat is called thermal conductivity.[1–4] Thermal conductivity in a solid can be expressed by the Fourier equation:[1–4] dQ/dt ‹ kA (dt/dx), where dQ is the amount of heat flowingnormal to the area A in time dt. Heat flowis proportional to the temperature gradient of dT/dx, and the proportionality ...
