no it will not.......well it could if you light it near the oxygen tanks but it should go straight up considering there is no wind unless you have people around you
Ahem - in orbit, no weight, so no convection to draw the flame up. The flame will form a sphere, and then go out, as diffusion cannot feed oxygen to the reaction quickly enough to keep the flame going.
the sphere i understand but wouldnt the fire keep going because there is oxygen
On Earth, you'd get a convection current - the hot, oxygen-depleted air rising and drawing in a steady supply of fresh oxygen-rich air.With no convection current, oxygen only spreads by diffusion (look it up) which is much slower than convection.That is also why spacecraft need fans - without breezes, people would suffocate in their own cloud of CO2.
ok ok I see now so it basically forms a "force field" (if you will) and dies under its own sourcesorry american high school science sucks these days
Not a force field (that's gravity, magnetism and electrostatics), but a "zone of depletion" - any oxygen molecule that bounces too close gets eaten by the reaction, until the immediate area is empty, and the flame starves.
ah! even a better simplistic answer than mine :-)
