Question

Variation of thermal conductivity of pure metals with temperature

Answer 1

In the case of pure metals and alloys, the thermal conductivity predominantly depends on electronic effect (flow of electrons) . As temperature increases, both number of free electrons and lattice vibrations increase. Thus thethermal conductivity of the metal is expected to increase.

Answer 2

Answer:

In the case of pure metals and alloys, the thermal conductivity predominantly depends on electronic effect. As temperature increases, both number of free electrons and lattice vibrations increase. Thus the thermal conductivity of the metal is expected to increase.
