- Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat. 
- Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds. 
- The body transforms the chemical energy in food into heat and mechanical energy. 
- At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.
