Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.Did you know that heat could be transferred between two bodies at different temperatures? In this discussion, we will look into the thermal properties of matter and will discuss various methods of Heat Transfer. We will also learn how to solve problems based on this concept.
