Help !! What energy is stored in fireworks ?

Question

Plz leave mi some answers. They would me most appreciated.

Thanx.

Answer 1

really loud and explosive.

Answer 2

The firework is ready to shoot out --->Chemical potential energy

The firework is shot out--->kinetic energy(known as moving energy)

Answer 3

Kinetic energy, the rapid expansion of hot gases expanding outward.

Answer 4

Chemical energy, which is a form of potential energy.  But the term "potential energy" is typically used only for gravitational potential energy.

Answer 5

potential energy

Answer 6

chemical->potential kinetic->kinetic+heat+sound

Answer 7

you can find it here! Good luck!!

Answer 8

Chemical energy is stored in fireworks.  Petrol will burn in air releasing energy but with fireworks the oxygen is supplied. Firworks are basically gunpower with metal salts added for colours.

Black powder is a granular mixture of

a nitrate—typically Potassium nitrate (KNO3)—which supplies oxygen for the reaction

charcoal, which provides fuel for the reaction in the form of carbon (C)

sulfur (S), which is also a fuel, lowers the temperature of ignition and helps increase the speed of combustion

Answer 9

potential energy.

Fire Works

I hate Fire Works. It is making Air Pollution & Noise Pollution also. It is spoiling by emiting Phospharous Gas, which is Danger for Health and Hearing Disorder amongChildren & Old Age Senior Citizens.

I  spent my Childhood near Sivakasi,Virudhnagar Dist in Tamil Nadu, India.

When any Burn Fire Crackers in Street, they not al clean the Street or my Concern People also not bother about Cleaning.

But they never clean the Street. They left as it is. It makes Air Pollution and it goes to Soil and spoil Water also.

Answer 11

unexploded ---> potential energy

after they explode ---> kinetic energy

Answer 12

its sodium and a type of metal in which the metal gives the color and when they r lit off they explode since the sodium is reactive

Answer 13

I'd guess chemical because the flame has to react with something

Answer 14

gunpowder..sparkles...the kind that light up!!

Answer 15

Nuculer

Answer 16

set one off in your hand, that would give you an idea.
