Question

What does the conductivity of metals
depend upon?

The nature of the material

Number of free electrons

Resistance of the metal

Number of electrons​

Answer 1

Answer:

nature of the material

temperature

Answer 2

Answer:

The conductivity of metals depends upon the number of free electrons.

Explanation:

A metal's heat conductivity is determined by the following factors:

• The number of electrons that are unbound.i.e.free.
• The speed of unbound electrons and, in particular, how far they can travel before colliding with atoms and changing their orientation.
• The existence of delocalized valence electrons is what gives metals their excellent thermal and electrical conductivity.

The correct answer is the number of free electrons.
