Fire + gravity

What does an open flame look like in a 0 gravity environment?

Flame always moves up no matter what. We just talked about that in training tonight.

Its a chemical reaction.

It will still move up. Either way it moves up from where it is. It defies gravity whether there is gravity present or not. Basically fire always goes for the highest place.

actually its energy in the form of heat and light coming from the chemical reaction.......

yeah everything isnt matttter either...........like my thoughts

if it always goes for the highest place, and in a zero gravity environment, there is no true up, then wouldn't it extend out in all directions and possibly extinguish itself? Just throwing in my theory.

I agree. Could there be fire in a zero gravity area? In space there is no oxygen, and fire needs oxygen.

That could be very well possible. After all there is no oxygen in space. And you have to have oxygen for a fire even if you have fuel.

Turn the gravity off in a space station obviously filled with oxygen, light a fire, what does it do?

I said that because people were talking about that fire needs oxygen, and there needs to be no gravity and nobody came up with a place where it could be done, so...

A fire has to be started from somewhere, it doesn't just spontaneously happen. In space it would move away from the source that ignited. Look at space shuttles. I'm not sure, I'm just guessing...

...but there can be fires in space if sustained by a source obviously. That's how we have rockets. There are chemicals that burn and create their own oxygen, making high atmosphere, and indeed zero-atmosphere flight possible!

if there can be no fire in space becous of no oxygen, then how do u explain a star(which is a burning ball of gas...)

fire is an energy.

in order for there to be the required gasses for fire to burn, you need an atmosphere, you cant have an atmosphere without gravity, so i dont think its possible, but theoretically, i have no idea.

In 0 G a flame would look like a ball cause gravity is what drives the convection currents(Hot gasses rising while cooler one fall) that give a flame it's shape he on earth will not form.

If you want to see the pict of one here ya go
