What happens when matter is altered?

When matter is altered, energy is involved in the process. Any change in state, composition, or arrangement of particles requires energy to break bonds, overcome forces, or reconfigure the material on the atomic or nuclear level. Energy can be absorbed or released, and it may appear as heat, light, motion, or other forms. This makes the option stating that energy results the best fit, because alteration inherently involves energy transfer or transformation. The idea that matter becomes energy would imply complete mass–energy conversion, which isn’t general for most alterations. Saying only heat is produced is too narrow, since other energy forms can accompany changes. And stating the matter remains unchanged contradicts the premise of alteration.
