Why do some metals conduct heat better than others?

A

Because of free electrons

B

Because they do not have any free electrons

C

Because of the difference in the strength of metals

D

All of above

Answer

The single biggest reason for the difference in the conductivities of metals is the difference in how far the free electrons can travel before they hit something. It turns out that the heat transfer is maximized when the substance has a perfect crystal lattice structure.
