Fourier’s Law of Heat Conduction

Fourier’s Law of Conduction states how much heat shall flow through a conductor bridging a thermal difference. This law was formulated by Joseph Fourier in 1822. [1]

Specifically, Fourier’s Law states that heat flow is proportional to the conductor’s area and the thermal difference bridged, and is inversely proportional to the conductor’s length.
