An endothermic reaction is when energy is absorbed. An exothermic reaction releases energy. At times, it is difficult to remember the difference. Answer and Explanation:1 The prefixes of the words help one to remember which is which. Thermionic is related to heat, like thermal underwear.You als...
The chemical reaction between cement & water, known as the hydration process, is an exothermic reaction. That is, heat is liberated during both the setting & hardening process of the concrete. The concrete expands as the temperature rises, & restraint against contraction on subsequent cooling, ...
