Understand the Problem
The question is asking about the factors that influence how heat moves from one body or area to another, specifically focusing on the principles of thermodynamics and heat transfer.
Answer
Temperature difference between two bodies.
The direction of heat flow is determined by the difference in temperature between two bodies, with heat always flowing from the body at higher temperature to the body at lower temperature.
