Answer» he difference between endothermic and exothermic REACTIONS lies in the words themselves. "Thermic" refers to HEAT, just as in the word "thermometer." "Exo" means "outside" and "endo" means "inside." Thus, an endothermic reaction pulls heat into an object or area, while an exothermic reaction expels heat. From this basic definition of the terms, you can understand a variety of other facts about these two types of chemical reactionFrom a chemistry standpoint, there is no such thing as cold -- only an absence of heat. Endothermic reactions draw heat energy into themselves. As that heat leaves the surrounding area, the temperature DROPS. For example, a chemical first aid cold pack works because of an endothermic reaction between WATER and ammonium nitrate. Because it pulls heat energy into the pack, the pack FEELS cold to the touch as it draws heat from the surrounding area. |
