What characterizes exothermic energy?

Exothermic energy is characterized by the release of energy, typically in the form of heat, during a chemical reaction or physical process. This means that when a reaction is exothermic, it proceeds by converting stored energy in the reactants into energy that is released into the surroundings, causing an increase in temperature. This characteristic is crucial in various applications, including combustion reactions and metabolic processes, where energy is harnessed to perform work or sustain life.

The concept of exothermic processes is fundamentally contrasted with endothermic processes, where substances absorb energy and often decrease in temperature. By recognizing that exothermic reactions release energy, it becomes clearer how they play an integral role in both natural and industrial phenomena, such as the combustion of fuels that powers engines and heating in homes.
