The process that causes fireworks to emit light is the excitation of an electron. When you give energy to an electron is a substance via heat etc. it is able to move up to a higher energy level. There is a set amount of energy between the energy state the the electron was in and now is in. The electron prefers to be in the lower energy state so releases some energy in the form of a photon which is a light particle. The energy of the photon depends on the distance between the 2 energy levels which in turn depends on the substance (copper, iron etc.). Different energies give photons of different wavelengths and therefore different colours

What other sorts of stress cause p lunula cells to emit light?
Mechanical stress causes p lunula cells to emit light.
Does the moon have an odor?
No. The moon is atmosphere-less, and the rocks there would not smell. But when moon rocks and soil are taken into a normal air environment, they do emit an odor that the astronauts likened to wet ashes or burnt fireworks.
Do dogs emit an odor when they are scared?
no they don't. I have got a dog and it never does that when it is scared.
Why are transition metals used to make fireworks?
The short answer is "because of the emission spectrum of the metal in question". When metal atoms are heated strongly, they emit light of a characteristic color, due to the atom's emission spectrum (this depends somewhat on the other atoms in the compound, but generally speaking this is a minor effect, shifting it from one shade of red to a slightly different shade of red rather than shifting it from red to blue). The particular metal salt used depends on what color you want the fireworks to be. For orangish-yellow, sodium salts work well; for red, you can use strontium salts, etc.
Do galaxies emit light?
Yes galaxies emit light
What are the three processes to cause fireworks to emit light?
space shuttles.
What three prosecess cause fireworks to emit light?
thing :P
What are bioluminous objects?
Things that shine - emit light - through biological processes. Fireflies etc
What are the two main mechanisms of colour production in fireworks?
One mechanism is; when the atoms of various metals are heated as in fireworks, the electrons are bumped into higher (energy) shells (orbits). When they (electrons) fall back into their normal shell they emit light of certain colors (frequency).
What does a star do?
Among other things, stars emit great quantities of radiation due to exothermic nuclear fusion processes.
What is Disadvantage of industry?
The main disadvantage of industries is the fact that they pollute the environment. Most industrial processes will emit pollutants into the environment.
What other sorts of stress cause p lunula cells to emit light?
Mechanical stress causes p lunula cells to emit light.
Harmful effects of radioisotopes?
Radioisotopes can emit harmful radiations that can cause cancer.
Does you body emit energy?
Yes, some tiny amount of energy as a consequence of electrochemical neural processes, but mostly infrared heat energy.
What are the processes by which an electric circuit can transfer energy to its surroundings?
emit heat emit light start a chemical reaction like say burning someone charge a substance with energy like a battery move something by turning to kinetic energy ... that's it for me :)
