chemical change

∙ 10y ago
When a firework is set off, a chemical reaction occurs inside the firework shell. The ignition of a fuse ignites the gunpowder, producing rapidly expanding gases. These gases create pressure, leading to the explosion of the firework shell. As a result, colorful sparks, flames, and loud sounds are produced. Fireworks can also contain various chemicals that generate specific colors and effects when they burn.
