How does heat transfer through conduction?

Answer 1

Conduction transfers heat from the warmer body to the cooler one. Energy flows (by molecular collisions and, in metals, moving electrons) from higher temperature to lower temperature until thermal equilibrium is reached.

So the correct choice is: "from the warm object to the cool object." (If air is between them, heat can still conduct into the air from a warm surface, but in fluids convection usually dominates the transfer away from that surface.)
