Can energy be created or destroyed why

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were r… WebSort of. Energy and mass are equivalent entities as governed by the laws of special relativity. Energy cannot be created or destroyed by any means, chemical or otherwise; however, it can be transformed from one state (e.g. matter) into another (e.g. heat).
