when energy changes form what kind of energy is released
The dry wood is a store of chemical energy. As it burns in the fireplace, chemical energy is released and converted to thermal energy (heat) and light energy. Notice that the wood now turns into ashes (a new substance). Food is also a good example of stored chemical energy.This energy is released during digestion.Molecules in our food are broken down into smaller pieces. As the bonds between these atoms loosen or break, a chemical reaction will occur, and new compounds are created.ood is also a good example of stored chemical energy.
