i think if energy is released it is either a chemical or physical change i hope this is right!:)
Any kind of energy can be released depending on the circumstances.
Chemical energy can change into just about any other type of energy.
radiant energy
electrical energy.
Electrical energy.
chemical energy
kinwtic energy
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.
heat
Heat And Kinetic Energy
Energy transformation
No, energy is absorbed instead.
