    Can a spark be created withought oxygen, i suspect yes but my physics is a bit rusty and im not too sure anyone know for sure?

    cheers

    Yes, yes you can. A spark is glowing hot material (usually metal), it can't ignite but it can still glow.

    A spark is just ionised gas, I see no reason why that gas has to be oxygen :confused:

    But i used diagrams to support my argument. Surely that means i'm right? :p

    I'd be more likely to believe me than you.

    i believe its yes as some of you seem to be confusing spark with burn, have definitive nasa analysis anywas so its all good.

    You used diagrams to support the no oxygen, no fire theory.

    Spark != Fire.

    You can get sparks in a vacuum without oxygen by incandescence. Apparently.

    Im going to say the same thing everyone else has said and yes. It's because the oxygen is a fuel in its self for a spark. It is it's molecular structure which favours the spark. I could be wrong though, i'm not much of a Chemist. I'm an A Level Physician and Mathematician.

    A-Level chemistry says you need no oxygen.

    Spark can be a glowing hot particle like metal flying off a angle grinder.

    Or an electrostatic discharge like a sparkplug which needs a gas to travel across.

    If enough oxygen was sealed in the cartridge for combustion to fully occur then yeah. :)
