Transfer of Thermal Energy

What is Transfer of Thermal Energy?
It is the transfer of thermal energy ONLY when there is a difference in temperature.

How does it occur?
Thermal energy always flows from region of higher temperature to a region of lower temperature.

When will it stop?
Transfer of thermal energy will only stop when a state of thermal equilibrium is reached between two bodies, when the temperatures are same, there is no net flow of thermal energy between them.

Thermal energy is transferred through:
-> Conduction
-> Convection
-> Radiation



Heat transfer video

This video shows how thermal energy can be transferred in 3 ways.[conduction, convection, radiation]. As the moving black part on the object shows the thermal energy being transferred from heat source onto the object.
