FIREWORKS
Thanks for listening!
Fuel
Oxidizer
Binder
Chlorine doner
Color-producing compound
decomposition to produce oxygen!
synthesis to produce hot gases!
Excited State
Ground State
photon
released and
light
produced!
Gunpowder
starch
DO YOU LIKE FIREWORKS?
LETS TALK MORE ABOUT FIREWORKS
hold mixture together and separate elements
help strengthen the colour
Ammonium perchlorate is the most common
used for shooting the aerial shell
reaction more
controlled
produce
three oxygens
used for
higher temperatures
more
stable
than chlorates
release
four oxygens
The hot gases released add to the
explosive force
of the reactions
stars
produce color by luminescence
Aerial shell
filled with gunpowder, stars, and a time fuse is placed in a
mortar
.
The
time fuse
ignites the
gunpowder in the shell
later in the sky and produces
fireworks
.
The fuel gets ignited and allows the stars to burn.
Time to learn about the equations!!
Saran
Dextrin
Red Gum
Shellac
Fireworks originated in
China
~2,000 years ago. Legend has it that fireworks were discovered invented by
accident
by a Chinese cook working in a field kitchen who happened to mix
charcoal
,
sulphur
and
saltpeter
.
It went boom!! and there were many colours that he found pretty.
YEAH YOU DO!!! Here's some brief history
A solid fact is that the Chinese did invent
gunpowder
though, in the 9th century, and it is a very important part of fireworks.
