  1. Chemical Kayla Starner and Abbey Taingay

  2. Definition of Chemical Energy Chemical energy is a form of potential energy. In the strictest definition, chemical energy is the energy involved in the bond formed between two atoms. Each bond within a chemical compounds involves different amounts of energy.

  3. Types of Chemical Reactions Some chemical reactions give off heat and some require heat to occur. Reactions that give off quantities of heat are called exothermic reactions. Our example of the explosion of dynamite is an exothermic reaction.

  4. Examples: Space Ship The thrust of the two solid rocket boosters is combined with the thrust of the three main engines on the Space Shuttle. The Space Shuttle engines are burning hydrogen with oxygen to make water (steam). The chemical equation is: 2H2+ O2 -> 2H2O

  5. Examples: Matches A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy.

  6. Examples: Car Engine Converts the chemical energy stored in the gasoline into mechanical and thermal energy.

  7. Examples: Fireworks Energy and force are tightly related. For example, force times distance is one way energy is calculated. Atoms that attract each other with a large amount of force are the same ones that take a lot of energy to pull apart. Instead of making force and energy two separate categories, I felt they are better grouped as one.

  8. Examples: Flashlight Converts chemical energy (stored in the battery) to electrical energy to light the bulb. The bulb converts the electrical energy to electromagnetic or radiant energy.

  9. Examples: Human Body Converts chemical energy stored in food into mechanical energy – for a beating heart and moving muscles.

  10. Examples: Candles Candles also possess a lot of chemical energy. So does petrol.

  11. Examples: Lightning Energy produced by chemical reactions like those that occur in batteries

  12. Balancing Chemical Energy Chemical Energy obeys the same kind of relationships that we expect for all forms of energy. Controlling the production and use of Chemical Energy is something that all life on Earth must master.
