CHEMISTRY

Energy can be defined as the capacity to do work.                        Forms of Energy The different forms of Energy are: 1. Mechanical energy  2. Chemical energy  3. Electrical energy  4. Heat energy  5. Nuclear energy  6. Light (Photon) energy  7. Sound energy  8. Magnetic energy  All matter possess energy in one form or the other. When energy changes from one form to another, the total amount of energy before and after the change are always the same. This is the law of conservation of energy.         The law of conservation of energy states that energy can neither be created nor destroyed but it can be changed from one form to another.       Energy changes in chemical reactions Energy changes occur during chemical reactions because the reactants and products possess different amounts of chemical energy. The forms of energy changes that m...
