WebHow Volume Affects Exothermic Reactions. Epoxy cures through an exothermic reaction. This means that as the molecules react they generate heat. The amount of heat depends on the thickness of the epoxy mass … WebThis investigation introduces the concepts of enthalpy (heat) of ΔH in the context of exothermic and endothermic reactions. To give students a deeper grounding in the basics and reinforce basic concepts covered previously, you may wish to review the mechanics of chemical changes, how to write balanced chemical equations, and the law of ...
