There are several different answers. The one I’m most familiar with is gunpowder. If you put a line of black powder down on the ground and lite it. It burns. If you take that same amount of black powder and compress it in a container that contains it you will get an explosion. The same thing is similar true of gasoline. Pour it on the ground it burns. Enclose it and let it turn from liquid to vapor and you will get a big explosion.
