	Exothermic - RecipeFacts (Site not responding. Last check: )
		In the physical sciences, the word exothermic, in contrast to the word endothermic, describes a process or reaction that releases energy in the form of heat.
		Chemical exothermic reactions are generally more spontaneous than their counterparts, endothermic reactions (heat is absorbed into the system instead of released).
		As stated before, exothermic reactions have a generally higher degree of entropy (randomness, basically) than endothermic reactions, and are much more spontaneous.
