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.

Question

slab of steel is 50 W. Assuming the temperature
difference of 10.0 K, find the area of the slab.
(Thermal conductivity of steel = 45 W/m K).
