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
Also, oxygen itself is not flammable. When you burn something you are creating a chemical reaction that combines the fuel, wood for example, with oxygen. The more oxygen available, the faster this can occur
