Is fire cold?

Is fire hot or cold? I mean, relatively to the avergage temperature of the observable Universe.

Well, according to this

• the average temperature by volume is determined by cosmic microwave background, around 2.7 K.
• the average temperature by observable mass is determined by intergalactic material, that is about 10'000 to 100'000 K.
• if there’s dark matter out there, that goes up to about 1'000'000 K.

A professor I asked told me something about the temperature of the cosmological constant, and that in different periods of the universe different contribution were predominant, but I didn’t understand it much.

So in the end, if we count mass, fire is pretty cold.
