The fire wood sends heat out in all directions. Warmed smoke filed air goes up the chimney. The outside of the metal fireplace gets very hot. The air that is heated above the fireplace gets pushed up by cool air. The room is filled with light from the fire. Is this convection, conduction, or radiation

Convection

Explanation:

Convection is a mode of heat transfer that involves the actual movement of particles. In this case the particles are air particles.

Since hot air is less dense, it is pushed up by the denser cool air. This process may continue indefinitely and a convection current is set up.
