Mechanisms
The fundamental modes of heat transfer are:
- Conduction or diffusion
- The transfer of energy between objects that are in physical contact
- Convection
- The transfer of energy between an object and its environment, due to fluid motion
- Radiation
- The transfer of energy to or from a body by means of the emission or absorption of electromagnetic radiation
- Advection
- The transfer of energy from one location to another as a side effect of physically moving an object containing that energy
