What is Heat Transfer?

What is Heat Transfer? In general, heat transfer describes the flow of heat (thermal energy) due to temperature differences and the subsequent temperature distribution and chang The study of transport phenomena concerns the exchange of momentum, energy, and mass in the form of conduction, convection, and radiation...
