Chemical energy is a type of energy that is stored in the bonds of chemical compounds, such as atoms and molecules. It is released when a chemical reaction takes place. Chemical energy is what holds the atoms in a molecule together and also what holds molecules in a substance together. The energy produced from a chemical reaction can be either absorbed or released. When energy is given off, it is known as an exothermic chemical reaction. Examples of chemical energy include:
-
Food: The chemical energy in food is converted by the body into moving mechanical energy and heat energy.
-
Batteries: Batteries store chemical energy that can be converted into electrical energy.
-
Wood: When wood burns, the chemical energy stored in it is released as heat.
-
Coal, petroleum, and natural gas: These are examples of chemical energy that can be converted into thermal energy when burned.
It is important to note that chemical energy is a form of potential energy, which means it is stored energy that has the potential to do work.
