A flame reaches a small container of gunpowder. The gunpowder ignites, releasing large amounts of energy. This causes the molecules in the gas which the combustion of gunpowder produces to move faster. Pressure increases until the container bursts open. Air around it is pushed away as white hot gas escapes in a flash of light, causing ripples of air to spread out from the firework. It is these ripples that the ear hears as sound.
how do firewrks explode?
fire works explode by a chemical reaction(explosive)
Because of the gun powder in the bottom of the firework! Because of the gun powder in the bottom of the firework!
Propagation rate of burn exceeds the speed of sound ...
i.e. it's a sonic boom.
Different fireworks make different sounds, there are crackers, bangers, whistling rockets, whizzers and choosers.
Fireworks have chemicals that burn to make colored lights.
The "formal" name of fireworks is "pyrotechnics"; this is not really a particularly "chemical" name.
you have to craft the firework with a dye.
he. they can explode any way. that's the reason you not want to stand near the big ones. don't hold them is your hands too.
it is a chemical change because when they explode they are no longer able to return to normal form.
Sound = light= kinetic= heat energy you can also find the answer at your science textbook
No, unless you burn them with it or explode it on them.
explode like real fireworks
Explode like real fireworks. Hope this helps!
Not in a cake, but on a cake because otherwise it will explode.
When Fireworks are made lots of different chemical powders are added and mixed to produce all the wonderful colours when they burn and explode.
usually things that explode and can fly arent good if they hit you.
no they do not expire, however they become unpreditable. they may explode instead of launching.

my jaw dropped open when i say the fireworks explode in the sinky twilight
