Question

Metallic conduction depends upon which of the following?

• A. The nature of the metal
• B. Number of valence electrons per atom
• C. Density of metal
• D. Temperature

Answer 1

Answer: (A)

The nature of the metal

For metals the thermal conductivity is mainly a function of the motion of free electrons.As the temperature increases the molecular vibrations increases so they obstruct the free flow of electrons thus reducing conductivity.
