  1. Chemical Energy By: Macey Lindberg & Giusi La Mattina

  2. Definition Chemical Energy- Energy that is stored in covealent bonds between atoms (Anglin)

  3. Chemical Energy • Chemical Energy- form of potential energy related to the structural arrangement of atoms or molecules. Chemical energy is stored in the structures of compounds and released when their structures are changed. • Chemical energy is potential energy. Chemical energy becomes thermal energy when it is burned.

  4. Overview of Chemical Energy Chemical energy is energy held in covalent bonds between atoms in a molecule. Every single bond has a certain amount of energy. Breaking the bond requires energy. The broken bonds join together to create new molecules, and in the process release heat. The burning of methane and oxygen is an example of this.(Chemical)

  5. Examples of Chemical Energy • Combustion- burning which creates heat and light energy (Anglin) • A match burns and the chemical energy produces heat and light energy.

  6. The sun is the ultimate source of energy for most living things on Earth Producers such as plants and photosynthetic bacteria and algae absorb light energy emitted by the sun usually in the form of glucose(Larocque) Glucose can be used by plants for their own energy needs or to consumers that eat the plants Photosynthesis Process of Photosynthesis (Larocque) carbon dioxide + water + sunlight  glucose + oxygen

  7. Metabolism • Photosynthesis and Glycolic create your metabolism. • Glucose- a simple sugar, as we extract energy from hydrocarbons and ethanol by oxidation with oxygen, we also get energy from glucose by oxidation. • Next process takes glucose to carbon dioxide and water Mteabolism

  8. Stored Chemical Energy Chemical energy is converted to thermal energy when we burn wood in a fireplace or burn gasoline in a car's engine. Biomass Petroleum Natural gas Coal

  9. Batteries Batteries are an example of chemical energy because the chemical energy is being transformed into electric energy when a wire is connected on both ends of the battery. The chemicals in batteries are zinc and carbon (Anglin).

  11. Fireworks • The heat from the flame moves down the fuse to create an explosion of the firework shell. Which then explodes and creates a firework.
