... reaction. The word exothermic comes from the root – “thermic”, which refers to heat, and the prefix – “exo” which means out of. Heat comes out of, or is released from, a reacting substance during an exothermic reaction. A reaction that involves burning, or a combustion reaction, is an example of an ...
