Question #3
The process of heat transfer in a solid metal rod is
A. Convection
B. Conduction
C. Radiation
D. Sublimation

Correct Answer: Option B


Explanation:
In solids, heat flows by conduction (lattice vibrations and free electrons). Metals are good conductors due to free electrons. Convection in fluids, radiation no medium.
