During a physical change, the matter of what the substance is made out of doesn't change.
Chemical energy is that energy contained in a chemical substance that is released when that substance reacts with another substance. For instance there the sucrose molecule stores chemical energy.
sugar provides energy for the body.
as you no chemical is the combination of two or more substance that is chemical energy is a energy found when there is chemical reaction

I think is a fuel in a substance that provides to form of energy such as heat, light, electricity, or motion as the result of a chemical change.

chemical change
No, condensing is a physical change, not a chemical change. It is the process of changing a substance from a gas state to a liquid state by removing heat energy.
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
