The swimmer's body contains a higher concentration of electrolytes (salts) compared to the freshwater lake A metal surface becomes dull because of continued abrasion. Both of the illustrated reactions are exergonic and release the same amount of energy during product formation. They are so excited that they jump an energy level and, in doing so, give off light. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core.
