Main Page | See live article | Alphabetical index Newton's law of heat conduction says that the heat flow is proportional to the temperature difference Δ T: dq/dt = K Δ T K is the heat resistance of the material over which the temperature difference is maintained. It is the thermal equivalent of Ohm's law for electric flow; although it is much older it is less known. See also: thermal conductivity This article is from Wikipedia.
