Question

in which direction does the transfer of heat normally take place

Answer 1

transfer of heat takes place from a region of high temperature to a region of lower temperature..and continues until both the temperatures become same

Answer 2

Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature, as described in the second law of thermodynamics. Heat convection occurs when bulk flow of a fluid (gas or liquid) carries heat along with the flowof matter in the fluid.
