Can a change in matter take place in which energy is neither released nor absorbed?

The principle called the conservation of energy is a concept from physics that states that the total energy in an isolated system can neither be increased or decreased. Because energy can neither be created nor destroyed it can only change form. An example of this would be transferring chemical energy into kinetic energy by combusting gas within a cars engine. The energy is neither created nor destroyed but the form of the matter simply changes.
