how can fire be different temperature?
In: Chemistry
The temperature of a fire depends on how much heat is being produced by the combustion and how quickly it dissipates. If you lit a candle, it will not produce a lot of energy, and this energy will dissipate quickly because the air all around the flame is cold, so the temperature will not be too high. In a big fire, a lot of energy is being produced, and the hot air in the center is surounded by more hot air, so the heat dissipates slowly. This causes the temperature to rise inside the fire. This is how a furnace works, you burn something that doesn’t necessarily produce a lot of energy (like wood) but this energy has nowhere to go, so the temperature raises a lot.
That’s why the “jet fuel can’t melt steel beams” meme is bullshit. The twin towers were essentially a huge furnace.
