In the given samples, heat flow due to conduction will occur in 2 Heat flows from faster molecules to slower molecules when they collide. Particles moving at a higher speed have a higher thermal energy, and heat energy moves from a region of higher energy to lower heat energy. Moreover, the mechanism of conduction relies on direct contact between particles. The only option that states these correctly is the second one.
