Fourier law of heat conduction

Fourier law of heat conduction

[′fu̇r·ē‚ā ‚lȯ əv ′hēt kən‚dək·shən] (thermodynamics) The law that the rate of heat flow through a substance is proportional to the area normal to the direction of flow and to the negative of the rate of change of temperature with distance along the direction of flow. Also known as Fourier heat equation.
