What is transfer of thermal energy?
It is the transfer of thermal/heat energy from a region of higher temperature to a rejoin of lower temperature so that the body and the surroundings reach thermal equilibrium.
However, if the two bodies have reached thermal equilibrium, with the same temperature, there is no net flow of thermal energy between them.
The three main processes whereby heat is transferred:
1. Conduction
2. Convection
3. Radiation
All the above processes can be seen displayed in the following pictures.
This video summarises conduction, convection and radiation.
Since this unit talks about thermal/heat energy, here's a clip on heat as energy!(:
