Description: Transcript: Chemical energy is a form of potential energy stored in the bonds between atoms and molecules. Chemical energy is released when electrons change their configuration in atoms and molecules. When wood burns, oxygen in the atmosphere reacts with the carbon to release energy. When gasoline or natural gas burns, long carbon chains are rearranged, and energy is released. In addition to being the chemical energy source of dynamite and all of our fossil fuels, all of the world’s rockets depend on chemical energy. When we eat we are extracting chemical energy from the food.
