Endothermic reactions are the opposite. The new bonds require more energy. This comes from heating the substances, or sometimes, comes from the surrounding environment. Absorbing heat energy from the environment makes everything decrease in temperature so the reaction 'feels' cooler.
Confidence votes 1.6K. If a reaction requires a constant input of energy, the products are higher in energy than the reactants. This type of reaction is known as endothermic, since it involves an increase in energy of the system. Conversely, reactions that release energy are known as exothermic.
