How does gravity work on a flame ?
Verified Answer
How does gravity work on a flame ?
When the low-density air got pushed up and out of the way by the oxygen-rich air, the fire got a new delivery of fresh oxygen to burn. Not so in zero gravity. The air that's is heated by the fire does expand, but with no gravity pulling denser air down into its space, it just stays there.
Without gravity, hot air expands but doesn't move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.
