A heat conducting rod, 0.30 m long, is made of an aluminum section that is 0.10 m long, and a copper section that is 0.20 m long. Both sections have cross-sectional areas of 0.00040 m2. The aluminum end is maintained at a temperature of 10°C and the copper end is at 170°C. The thermal conductivity of aluminum is 205 W/m • K and of copper is 385 W/m • K. Steady state has been reached, and no heat is lost through the well-insulated sides of the rod. The temperature of the aluminum-copper junction in the rod is closest to

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.
