Fire is a mixture.
Look up mixture and all of its forms: emulsions, solutions, gels, sols, etc....
When trying to find out what something is, always start with a mixture.

Mixtures can have properties that what is mixed do not have.

Basically yes. Its slightly ionized. Plasma doesnt have to be fully ionized plasma to be plasma.

>>14618975
what does "slightly" and "fully" ionized mean?

>>14618848
It can be, but the flame on something like a match is almost entirely just incandescent gas.

>>14619034
*gas with incandescent solid particulates.

So whos right

>>14619090
me obviously

In a plasma some of the atoms and molecules are not electrically neutral. They are ionized but usually its just a fraction like 0.1% of all atoms would be ionized. In a place like the center of the sun or a Tokamak they would be 100% ionized. Both are still called plasma according to current semantic conventions

>>14619090
Incandescent gas is also plasma. What makes it plasma is having ionized particles

Does /sci/ know anything?

in H2O with no impurities, .00001% of the H2O atoms ionize into H and O ions. is water a plasma?

>>14619129
yes that's why we call it "blood plasma"

>>14619129
I considered that. More to the case, in a salt solution theres a high density of ions. It can behave as a plasma to some level. Soientists like to say common fire is not a plasma because the ion density is too low, i dont know what the cutoff is. I believe fire is a plasma because it has many obvious visible plasmoid behaviours such as being influenced by a magnet

its got some plazzy

>>14618848
Fire can be plasma but not all fire is plasma.

>>14620468
name 1 fire that isnt a plasma

>>14619861
>being influenced by a magnet
I wish to know more. I've only found some youtube videos where the guy holds the magnet too close to the flame and the resulting effect is consistent with and may therefore be the result of Bernoulli acting on the updraft associated with the flame.
