Remaining: Flame in the world; Appropriate: Flame over the ISS The popular distribution of a flame below regular gravity circumstances depends upon convection, as soot has a tendency to rise to the very best of a basic flame, as in a very candle in ordinary gravity ailments, which makes it yellow. In microgravity or zero gravity,[71] including an atmosphere in outer space, convection now not takes place, plus the flame becomes spherical, with an inclination to be much more blue plus much more productive (even though it might go out Otherwise moved steadily, since the CO2 from combustion isn't going to disperse as commonly in microgravity, and tends to smother the flame).
