Been thinking about different atmosphere’s for sci-fi planets and the like, and I know that (allegedly) if there was 5% more oxygen on earth, then bugs and insects would grow to be much, much larger. Apparently the higher oxygen concentration in the early years of our planet is why there was so much megafauna (smth about cyanobacteria?), but how would that affect the way things burn? Since oxygen is incredibly flammable, I would assume that more oxygen = bigger flame, but usually that’s pure oxygen.
tl;dr
How does oxygen concentration affect the way things burn?
In: Chemistry
Dont think the percentage would effect the burning temp. However longer burning time would make it seem like it’s hotter when you calculate temp from convective and conductive heat transfer. I bet radiative heat transfer would remain the same.
As fore easily part, ofc yes. Oxidation of iron is burning so the more % you have, easier the burning.
