HOW DOES THE HEAT ENERGY GET FROM THE HOT WATER TO THE OUTSIDE OF A RADIATOR?

I REALLY NEED SOME HELP![*(]

Energy tends to move in the direction from hotter to colder. The metal of the radiator conducts the heat energy to the outside of the radiator where the colder air recieves it and rises away pulling more cold air after it to be heated, as well as radiating the energy to the surrounding walls, furniture, people, etc.

Yeah, but since the temperature is usually not all that high (hot water systems max out at about 180F) and they generally rely on airflow and surface area, its really more of a "convectiator." (if thats not a word, I get the copyright)

A tube or channel that is fitted with fins effectively and dramatically increases the surface area thermal transfer potential. The key is surface area.
