In a conduction heat transfer process through a solid slab layer taking place under steady-state conditions, the following temperature profile is observed. Ax L However, conduction heat transfer in radial direction through a cylinder (again under steady-state conditions) does not yield such a straight line for the temperature profile, but the following one: T T2 Ar Why?

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.
