When gunpowder explodes, it changes from a solid to a gas. That is why a gun works. Put a stick of wood on the fire. Watch the carbon burn as it turns to carbon dioxide. Feel it give off heat. Put gasoline in your car. When the gasoline combines with air it burns and turns to water and carbon dioxide. It also turns to hot gas and pushes your car.
