how is chemical energy useful

Best answer

Humans consume chemical energy contained in food. The food we eat contains stored chemical energy. As the bonds between the atoms in food loosen or break,a chemical reaction takes place,and new compounds are created. The energy produced from this reactionkeeps us warm,helps us move,and allows us to grow.

Chemical energy is energy that is stored in the bonds between chemical compounds, such as atoms and molecules. A chemical reaction is the process of atoms being rearranged due to a chemical change, resulting in a new substance being produced. An exothermic reaction is a form of chemical reaction when heat is produced as a by-product.

We all use chemical energy every day to perform daily functions 鈥?you’re using chemical energy right now to read this page! When we burn Natural Gas, the chemical energy is converted into light and heat. Chemical energy is energy that is stored in the bonds between chemical compounds.

When a chemical reaction takes place, the stored chemical energy is released. Heat is often produced as a by-product of a chemical reaction 鈥?this is called an exothermic reaction. How is chemical energy used?

natural gas – combustion reaction converts chemical energy into light and heat. food – digested to convert chemical energy into other forms of energy used by cells. cold packs – chemical energy is absorbed in a reaction. propane – burned to produce heat and light.
