1. Chemical Energy Chemical energy is the energy of rearranging atoms
The atoms of a compound are rearranged to form new compounds
Since work was done to join or bond the atoms together, when they are broken apart and rearranged energy is released
Example: Burning wood

5. Chemical Energy You take in the plants sugar by EATING!
Your body gets it’s energy by breaking the bonds in food and then performs energy conversions
You convert chemical energy in the food to kinetic energy when you are active and convert it to thermal energy to maintain body temperature

6. Why is the sun the ultimate energy source on our planet?
