>From my freshman year Applied Physics textbook:
"Conduction is the process in which heat energy is transferred by adjacent
molecular
collisions throughout a material medium. The medium itself does not move."
"Convection is the process in which heat is transferred by the actual mass
motion
of a fluid."
"Radiation is the process in which heat is transferred by electromagnetic
waves."
and that is how it will all happen.
