I was wondering why a lightning bolt is coined as "plasma", or a "spark" from an electrical wire/device is as well, yet flares, molten lava, and burning buildings are not(flares are pyrotechnic, exothermic, and very much like flames).
I hear arguments saying that plasma is ionized gas, but how can a flare not be ionized at such high temperature(and why isn't ionized, very hot flames considered plasma)?
This guy, the top answerer, says that fire is not plasma because it's not ionized:
Also, some lava exceeds 3,000 Fahreheit. How is that not plasma, and what draws the fine line between plasma and fire itself(not as a state of matter, but as a relation with gas)?
Fire is gas, but some say it's plasma if you can see it (check the link the poster added below in the first comment), so when does it become a full-on plasma if it's not normally one?
