What effect does an exothermic reaction have on temperature?

An exothermic reaction is characterized by the release of energy, primarily in the form of heat, into the surrounding environment. This release of heat results in an increase in temperature, which you would feel as warmth if you were near the reaction.

When an exothermic reaction occurs, the overall energy of the products is lower than that of the reactants, causing energy to be released. This release can significantly elevate the temperature of the surrounding area, making it feel warm or even hot depending on the scale of the reaction.

In contrast, other reactions, such as endothermic reactions, absorb heat, resulting in cooling sensations and a decrease in temperature in their environment. Here, the distinction lies in the direction of energy transfer—exothermic reactions are defined by their heat-releasing nature, distinguishing them from other types of reactions that take in heat or maintain temperature.
