Where does the heat come from a firework iS SET OFF?
The flame
What energy source starts a firework?
heat energy
What makes different colours in a firework?
We did this experiment in chemistry (well something like it). There's different chemicals that is out into the powder. The chemicals react differently when exposed to heat therefore when exposed to the extreme heat of the small explosion, the chemicals give off a certain color. The color depends on the chemical.
Why will a firework eventually go out?
because there is not enough heat for it to last and it i running out
Do a firework have heat energy?
Yes it does cuz when u lite it up the heat goes to the powder and ...KABOOM !! (Its called Thermal energy)
What series of events take place once a firework shell is ignited?
heat, sound & explosion is evolved
Where does the heat come from a firework iS SET OFF?
The flame
How is fierworks made?
a chemical reaction is made inside the firework itself. the heat from the fuse causes an explosion of metal. salts (not table salt for food) inside the firework also explode with the metal and creats the color.
What energy transfers in a firework?
Energy in firework is present in form chemical energy which will be converted into light and sound .and small part of energy is converted heat .then the remaining energy is converted into kinetic energy after explosion.
Are Exploding fireworks kinetic or potential energy?
They "are" neither; an object HAS energy, but saying that it IS energy is not entirely correct.Before it explodes, a firework has chemical energy. After the explosion, this energy gets converted to heat, and to kinetic energy.
Where does the heat come from when a firework is set ff?
the match

Does an ice cube have more or less heat than a firework spark?
Less. Firework spark is generated by fuse friction, ice by freezing water and the water expands.
Why do fireworks generally explode symmetrically?
The packing of the firework contains the explosive charge. When it is ignited the force radiates in all directions at the same time. Think of it as a lightbulb that is turned on. The light from the bulb goes in all directions at the same time. It is much too fast for you to see. A firework does the same thing only you see the burning pieces moving away from the explosion. They form a sphere.
