Compare endothermic and exothermic reactions in terms of potential energy, heat flow, and observed temperature changes. Explain your answer in complete sentences.

An endothermic reaction happens when the system absorbs energy from the surroundings, in the form of heat. An increase in energy most likely means the temperature of the predicts will  be greater than the temperature of the reactants.
Exothermic reaction: The system gives off energy to its surroundings, it loses heat during the reaction. Therefore, the products will most likely have a lower temperature than the reactants.

Heat flows from the reacting substances out to the surroundings in an exothermic reaction.


The thermal energy of the surroundings increases as a result of an exothermic reaction.


Heat flows in to the reacting substances from the surroundings in an endothermic reaction.


The thermal energy of the surroundings decreases as a result of an endothermic reaction.
