Conduction is the term for the heat energy transfer caused by the vibration of molecules at their positions.Convection, on the other hand, is the term for the heat energy transfer caused by the motion of molecules themselves, and radiation is the term for the heat transfer caused by electromagnetic waves. When water is poured in an extremely hot pan, the molecules in direct contact with the pan become heated. 

Eventually, these molecules migrate away, enabling the cooler molecules to settle down and become heated. Convection is the term used to describe the motion of hot molecules.

The energy that emanates from a source and moves through space at the speed of light is referred to as radiation. In addition to being accompanied by an electric field and a magnetic field, this energy possesses wave-like characteristics. Electromagnetic waves can sometimes be referred to as "radiation."
