Two rods ( fins) having same dimensions , one made of brass ( k = 85 Wm K) and the other of copper ( k = 375 W/m K ) , having one of their ends inserted into a furnace . At a section 10.5 cm a way from the furnace , the temperature of brass rod 120oC . Find the distance at which the same temperature would be reached in the copper rod ? both ends are exposed to the same environment .

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
