It is called an ENDOTHERMIC REACTION when the temperature decreases. More energy is needed to break the bonds in the reactants than is released when the new products are formed. ENDO = Inside or Internal Thermic = thermal/heat ENDOTHERMIC= The heat energy goes INTO breaking the bonds of the reactants. Does an endothermic reaction get hotter or colder when it is complete? Colder Two types of thermal change: energy is (The matter being changed absorbs Endothermic: taken in or absorbed. the heat so it feels cold.) Exothermic: energy is given off or released. Combustion is an example. (The matter feels warm or hot.) Label the diagrams below! Endothermic Exothermic During the 4 min video on endothermic and exothermic reactions, make sure you write down at least 1 real-world example of each type of reaction:
