Can you light fire in zero gravity?

FLAME IN MICROGRAVITY is spherical owing to a lack of buoyancy and convection. The flames didnt self-extinguish because the launch pad was not a gravity-free environment. Oxygen could still reach a flame in a gravity-free environment if someone blew the gas into the flame or let it “diffuse” in.

Why is a flame round and blue in zero gravity?

Why? A microgravity flame forms a sphere surrounding the wick. Diffusion feeds the flame with oxygen and allows carbon dioxide to move away from the point of combustion, so the rate of burning is slowed and it is an almost invisible blue color.

What is the shape of flame?

2a), the flame is basically symmetrical and cone-shaped, an axis of symmetry can be assumed to exist along the vertical centerline of the flame.

What will be the shape of the candle flame in space where gravity is absent?

A candle flame in zero gravity (as on the space station) is indeed quite different than a candle flame down here on Earth. In zero gravity the flame is spherical, blue, and centered on the candle wick. On Earth a candle flame is teardrop-shaped, yellow, and mostly well above the wick.

Does fire follow gravity?

Fires on earth are anchored by gravity, but the combustion gases are hot and light, so they rise. As the flame goes up, more air is sucked into the base of the fire, feeding more oxygen to the fire and making it burn more strongly.

What will be the shape of candle flame in space where gravity is absent?

In zero gravity the flame is spherical, blue, and centered on the candle wick. On Earth a candle flame is teardrop-shaped, yellow, and mostly well above the wick.

Why is a candle flame shaped like a teardrop?

The familiar teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker. Oxygen and fuel combine in a narrow zone at the surface of the sphere, not hither and yon throughout the flame.

Can you have oxygen in zero gravity?

A person needs air (oxygen) to breathe, but as long as they have it, then it does not matter whether or not there is also gravity. So as long as there is air in the space ship, you can breathe it, even if there is no gravity.

How does fire work in zero gravity?

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.
