Question

 One end of a rod of copper is placed in hot water. Thermal energy travels along the rod to make the other end warmer.

What is the behaviour of the copper at an atomic level that accounts for most of the transfer of thermal energy from one end to the other?
A Atoms at the hot end gain kinetic energy and move towards the other end.
B Atoms at the hot end expand, colliding with other atoms and transferring energy.
C Free electrons at the hot end gain energy and move towards the other end, colliding with atoms along the rod.

D Free electrons at the hot end gain energy from the hot water and move directly to the other end.

Answer/Explanation

Ans:C
