Within a room containing air, heat can transfer from one location...

Heat transfer in a room containing air can occur through all three modes: conduction, convection, and radiation.

Conduction takes place due to the collision of air molecules, though it is a slow process since air is a poor conductor.

Convection occurs as heated air becomes less dense and rises, creating convection currents that transfer heat effectively.

Radiation involves the transfer of heat through electromagnetic waves, which can travel through the air from warmer objects to cooler ones.

Thus, heat can transfer from one location to another by all the three modes.
