Consider two different rods.The greatest thermal conductivity will be in the rod with
A)electrons that are freer to move from atom to atom.
B)the greater specific heat.
C)the greater cross-sectional area.
D)the greater length.

Question

Quizplus · Accepted Answer

The greatest thermal conductivity occurs when there are more free electrons available to move and transfer heat energy from atom to atom. Therefore, the rod with electrons that are freer to move from atom to atom will have the greater thermal conductivity.
