Question

define and explain heat transfer​

Answer 1

Answer:

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

Answer 2

Answer:

The generation, use, conversion, and exchange of thermal energy between physical systems is the subject of heat transfer, which is a branch of thermal engineering. Thermal conduction, thermal convection, thermal radiation, and energy transfer through phase changes are all examples of heat transfer mechanisms.
