What things use chemical energy?


Quick Answer

The human body, kitchen stoves and even plants all use some form of chemical energy. Chemical energy is considered one of the more abundant forms of energy available.

Because chemical energy occurs between the bonds of two different chemical compounds, scientists are able to study this energy resource in a wide range of samples. The human body produces chemical energy through the process of cellular respiration. During this process, the body breaks down stored sugars, typically glucose, and uses the released energy to make adenosine triphosphate molecules, which the body can use for sustaining life.

Chemical energy produces either an endothermic or exothermic reaction. Whether the chemical energy is hot or cold depends on the new chemical bonds that are formed during the chemical reaction. Chemical energy provides the heating or cooling that occurs in a variety of sports packs when a particular chemical is combined with water.

All plants use chemical energy as well. Photosynthesis converts sunlight into energy for plant growth using a process of chemical reactions. Campfires, or any flames, exhibit an exothermic chemical reaction. The heat produced is chemical energy; as the bonds between the molecules within the fuel begin to break, the reaction produces heat and light.
