Heat conduction is the transfer of heat through a material without any movement of the material itself. In this case, the heat is transferred from the end of the rod in the fire to the other end of the rod through the material of the rod itself, without any movement of the rod. Heat convection, on the other hand, requires a fluid medium such as air or water to transfer heat, and heat radiation involves the transfer of heat through electromagnetic waves. Thermal expansion occurs when a material expands or contracts in response to changes in temperature, which may occur as a result of heat conduction but is not the main mechanism at work in this scenario.
