Why is the flames of a fire orange?

Question

I have noticed that anytime there is a fire the flames are orange and it dose not mater what is burning, the flames are the same colour.

Answer 1

If you can "see" an orange flame, you are observing photons of a specific range of wave lengths. Photons are produced during combustion as electrons of atoms (or molecules) drop from higher energetic orbits to lower and less energetic orbits, giving up their energy. The specific color relates to specific chemical reactions and orange in not the only color that can be produced by a flame. If colored Christmas wrappings are burned, the metals in the pigment can give off a variety of colors including green for copper. The flame produced by burning wood (or even a candle) involves the combustion of carbon and hydrogen (hydrocarbons) at limited temperatures and that produces orange. If the flame was much hotter (using pure oxygen?) and electrons were driven to even higher orbits before returning to rest orbits, perhaps the color would be nearly white, like the sun. Of course many of the photons (infra-red and ultra-violet) that reach your eyes are entirely invisible. Hope that helps a little.

Answer 2

Its the color given off by Carbon. when Carbon atoms are heated and release that energy back it is in the orange spectrum of light. Different things do burn at different colors as well. But, for most carbon is the byproduct you see in the flame.

Answer 3

The particles in the the flame are heated and they glow

If you burn natural gas is is blue

Answer 4

It is mainly because Sodium contaminates everything. And the flame indication color of sodium is orange. Other chemicals have different colored flames.

Answer 5

It has to do with the type of combustable mater you are using. Also color indicates heat levels, ie cool heat.

Answer 6

different things burn different colors, has to do with the chemicals salts in them, and the amount of heat.
