Facts about thermal conductivity

The effect of temperature on thermal conductivity is different for metals and nonmetals. In metals, heat conductivity is primarily due to free electrons. Following the Wiedemann–Franz law, thermal conductivity of metals is approximately proportional to the absolute temperature (in kelvins) times electrical conductivity. In pure metals the electrical conductivity decreases wit… WebDec 9, 2014 · Heat can only be transferred through three means: conduction, convection and radiation.
