Is it possible for a substance to undergo combustion at a temperature lower than its ignition point if the concentration of oxygen increases?

    $\begingroup$ You asking a very general question for which there are likely to be exceptions. However, in general, if the oxygen concentration goes up (e.g. replacing an inert gas) then it would be easier to ignite the substance. The most notable exception is too much oxygen. Since ignition is a chain reaction, there has to be enough of the substance too. $\endgroup$ – MaxW Aug 9 '18 at 18:36
  • $\begingroup$ i feel this question very interesting since i thought the same way. I also wish to test impact of air pressure on combustion if possible someday. $\endgroup$ – Always Confused Sep 1 '19 at 16:57
