Question 9 the dimensions of the faces of each block be 3 m by 2 m. Also, the conductivity of copper is 200 and the conductivity of iron is 300 K: If the left face of the copper block is A 20 cm thick block of copper is placed against a 40 cm block of iron. Let m K 100°C and the right face of the iron block is at 10°C, calculate: (a) the temperature between the blocks (the interface).

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.
