What is the temperature of fire?

  • Answer:

    Fires give off heat, or the process of energy transfer from one body or system due to thermal contact. Typical temperatures of fires and flamesOxyhydrogen flame: 2000 °C or above (3645 °F)[7] Bunsen burner flame: 1,300 to 1,600 °C (2,372 to 2,912 °F)[8] Blowtorch flame: 1,300 °C (2,370 °F)[9] Candle flame: 1,000 °C (1,830 °F) Smoldering cigarette: Temperature without drawing: side of the lit portion; 400 °C (752 °F); middle of the lit portion: 585 °C (1,085 °F) Temperature during drawing: middle of the lit portion: 700 °C (1,292 °F) Always hotter in the middle. Temperatures of flames by appearance A Fire at 1/4000th of a secondThe temperature of flames with carbon particles emitting light can be assessed by their color:[10] Red Just visible: 525 °C (977 °F) Dull: 700 °C (1,292 °F) Cherry, dull: 800 °C (1,470 °F) Cherry, full: 900 °C (1,650 °F) Cherry, clear: 1,000 °C (1,830 °F) Orange Deep: 1,100 °C (2,010 °F) Clear: 1,200 °C (2,190 °F) White Whitish: 1,300 °C (2,370 °F) Bright: 1,400 °C (2,550 °F) Dazzling: 1,500 °C (2,730 °F)

Depends on what you are burning and the conditions. If you burn coal in an open fire it will burn inefficiently and at a lower temperature producing carbon as well as oxidation products. When coal is burnt in a power station, or on a ship, the conditions are optimised for combustion giving no carbon and just oxidation products and none combustible materials. These have different temperatures, the more complete the combustion the higher the temperature. Consider the combustion of acetylene. When the welder lights his torch he has just acetylene, giving a yellow flame and soot ( carbon ) . Temperature maybe 1000C Then he adjusts the torch, feeding more oxygen into the flame, this now turns a white colour and roars giving a temperature of over 3,000 degrees C, which easily melts steel.

All substances have different flash points. The flash point is the temperature at which the substance ignites. Coal will burn much hotter than natural gas for example, so a coal fire has a specific temperature and a NG fire has a different temperature. Complete or incomplete combustion will also have an effect on fire temperature.

It absolutely depends on what is burning and where it's burning (the environment). Fire is a product of some chemical reaction such as oxidation. Different materials may oxidize with different temperatures. For example a candle burns at 760 degrees C, but napalm burning reaches temperatures of 1250 degrees C.

thats a very well asked question........... actually fire is hot,very hot... actually very very hot but temp measuring instrument cant be put into it i think u would understand k fire ka kaam is jalana so whatever we will put surely jal jayega na..... so i dont think we could measure the temp. acurately aur vaise bhi fire to hilti rehti hai. so temp. kiska check karege??????

It depends on the substance being burned. A Bunson burner for eg, has a temperature of 300 centigrade (572 F) Every flame has it's own temperature.

Fire actually has a large temperature range based on its fuel and oxygen supply.

depends upon the substance, fuel and surroundigs.

it's hot? like something degrees farenheit.

Its too HOT, can feel the temperature by touch & it varies on time.
