Ok then. Btw, the explosion is cause by the release of energy after the build up. Sure, things get hotter. But what gets heated can only hold so much of it. Most things would melt from solid to liquid, or evaporate to gas. But air moisture/water vapor/air itself/etc. are already in gas form... Every single one of those are in gas form, so they can't evaporate into anything. So there comes a point where it gets too hot. Eventually, they get too hot to hold the heat, and it all escapes at once in a massive release of energy. In other words, it explodes.

It's because of the limit to how much heat the surrounding environment can hold.
