A hot metal rod transfers heat to its cooler end. What form of heat transfer is this?

Heat moves through a solid like a hot metal rod by conduction. In solids, energy is transferred from the hotter region to the cooler region through collisions and interactions between particles, and in metals, free electrons carry energy rapidly from the hot end toward the cooler end. This transfer happens without any mass movement or phase change, so it isn’t convection or evaporation. It also doesn’t rely on radiation, which would send energy as waves without needing direct contact. So the best description here is conduction.
