What is the temprature of Fire?

Answer 1

Depends upon the COLOR of the fire.

Look up Wien's Displacement Law.

Basically (all) objects at the same temperature emit the same peak wavelength:

λmax = 0.002898/T where λmax is the maximum wavelength and T is the temperature in Kelvin

for example, a red flame has about λmax =630nm so this is about 4600K while a green flame has about λmax =530nm so this is about 5500K


Extra: Average Human Temp is 98.6 F → 37C → 310K
so peak wavelength is:

λmax_human ≈ 0.002898/310
λmax_human ≈ 9.4μm which is in the Infrared region of the EM spectrum

Answer 2

There are several kinds of fire tempertures so you have to clarify what each one it is before you can arrive at this answer. An easy way to answer this was a scifi movie from a few years back called Fahrenheit 451, which gets its title from the temperature at which paper combusts. The movie is set in the future when books are banned and thrown into huge fires. This horrible event has happened at least three times in history that i know of - from the Emperor Chin - founder of China in BCE (he wanted history to begin with him), to the burning of the Great Library of Alexandria (accidentally ? by Caesar), to Hitler in the 30's (again, so history could begin with him and end "Jewish and other Radical" thoughts from the German people. But i digress and must restate that fire can be at several different tempertures depending on the type of fuel and/or accelerant (wind, propane, acetylene, etc.) As i was not real good at science i suggest you ask a fireman or your local librarian for help on this question and remember that different types of fires have different temperatures. hope this helps, at least, in part.

Answer 3

I'm willing to guess it's between 500ºF and 1000ºF, that's purely my personal guess. I've baked items camping in dutch ovens and the nature of the dutch oven is that you put hot coals into a pit and "bury" the over in ther with it. Our combination of red hot embers from pine and maple wood, (not actually flaming) cooked a bread item that was equal to cooking power of 450º to 550ºF. I would assume denser wood would burn hotter, such as oak, few people know this, but the inside of the wood is what actually burns, even though the human eye sees the flame on the surface the actual "fuel" is inside. (Sorry, I can't explain the exact science of it.)

Other items of course burn at all different temperatures, if I remember correctly magnesium burns at about 1800º, which is why they sell it at Walmart as a fire-start on a bar which you scrape the dust of it off.

Answer 4

The type of fuel and the fuel/Oxygen ratio are the defining factors to determine the temperature of fire. Some fuels will burn hotter than others under normal conditions, and if you modify the conditions so that the combustion reaction is optimized different fuels will still release different amounts of heat and therefore have different temperatures.

Answer 5

Combustion temperature and flame temperature a very different.
A flame is the glow of hot gases that are a product of combustion and typically are around 500 degrees although they can be produced under certain conditions at a much higher temperature as in an oxy/acetylene torch. combustion temperature can be many thousands of degrees and is soley determined by the material under going combustion and the pressure that the combustion is under.

Answer 6

Depends Upon The material That is Burning

Answer 7

That depends upon what's burning, and under what conditions. See the table at the bottom of the page for some typical flame temperatures for welding apparatus (reference 1).

Answer 8

The temperature of fire varies depending on the source of fuel.

Answer 9

stick your happy thing in the fire and you tell me!

on second thought that was only a joke DO NOT DO THAT!
it was only a joke Dave. LOL

but fire can be a wide range and degree of hotness due to type of fual and substance that is surning

Answer 10

Depends.

Books 451F
Surface of the sun 6,000 C
Inner core of sun 23.000,000 K
