Why does burning fuel give off so much energy?
Light a match, toss a log on the fire, hit the gas pedal — somewhere, fuel is burning, and out comes warmth, light, and oomph. But where was all that energy hiding? It wasn't in a tiny battery inside the wood. It was hiding somewhere much sneakier: in the way atoms hold hands.
Everything around you is made of atoms, and atoms love to stick together. When two atoms join, they form a bond — think of it as a stretchy spring connecting them. Some springs are loose and lazy. Others are pulled tight and tense, holding a lot of squished-up energy, just waiting for a chance to relax.
