Remaining: Flame on Earth; Right: Flame within the ISS The popular distribution of a flame under typical gravity ailments depends upon convection, as soot tends to rise to the highest of the normal flame, as in a candle in typical gravity ailments, which makes it yellow. In microgravity or zero gravity,[seventy four] which include an atmosphere in outer Area, convection not click to read more occurs, as well as the flame gets spherical, with an inclination to be additional blue plus more economical (even though it may head out Otherwise moved steadily, given that the CO2 from combustion does not disperse as readily in microgravity, and tends to smother the flame).
