Is higher thermal conductivity better

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… WebThermal conductivity is a measure of how well a material conducts energy when it is heated. Some typical values of conductivities are: This means that 385 joules (J) of energy will flow per...
