For heat flow, the heat equation follows from the physical laws of conduction of heat and conservation of energy (Cannon 1984). By Fourier's law for an isotropic medium, the rate of flow of heat energy per unit area through a surface is proportional to the negative temperature gradient across it: where is the thermal conductivity of the material, is the temperature, and is a vector field that repres… WebHeat and temperature are two different but closely related concepts.
