A flame has the classical teardrop shape because of convective air flow; as the hot, thin air rises (less dense things rise, while more dense fluids sink), the combustion process is carried up with it. Cool dense air flows in below it, providing fresh oxygen to the flame.
In zero-G, hot things don't rise and cold things don't sink. (With no gravity, which way would be "rise" and which way would be "sink"?) Hot gasses expand - but there's no gravity to pull cold, dense material down and allow the hot, thin gasses to rise.
So in zero-G, a flame is circular - until it goes out, snuffed by the carbon dioxide that gathers around it. With no convection, fresh air can't get to it.
If you wanted to burn a candle in the space station, you would need to provide a tiny fan to blow the CO2 away and blow fresh air in to the flame. Of course, this would be an INCREDIBLY STUPID THING TO DO, because oxygen is precious and expensive; it has to be flown up by rockets!
What else can I help you with?
When does the change in entropy equal zero?
The change in entropy equals zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
Is G at equilibrium equal to zero?
Yes, at equilibrium, the standard Gibbs free energy change (G) is equal to zero.
If the temperature changes by 100 K by how much does it change in and degC?
A temperature change of 100 K is equivalent to a change of 100 degrees Celsius. This is because the size of a degree Celsius and a Kelvin is the same, but the zero point is different (0 K is absolute zero while 0°C is the freezing point of water).
Is water freezing at zero degrees Celsius physical or chemical change?
Water freezing at zero degrees Celsius is a physical change. This is because the change in temperature causes the water molecules to slow down and form a solid structure, without altering the chemical composition of water.
IS stone combustible or not?
Stone is considered to be non-combustible. Stone has no fire rating at all. Stone has been tested before and shows zero fire hazard and shows zero flame spread.
Does the shape of red blood cells change in space?
no. it remains at it is even at zero gravity
What would be the shape of the candle flame inside a spacecraft?
In a zero G spacecraft, it would be just a small sphere of flame that lasts a couple of seconds and goes out..
Did the zero gravity pen change any when it is used on earth?
The zero gravity pen has never been changed or updated because it is almost flawless and nobody has anything to add to it.AnswerThe zero gravity pen relies on the polarity of water in the ink to induce the capillary action to draw ink down to the ball of the pen. Since this doesn't rely on gravity, there is no change when the pen is used on earth.
How much zero gravity is there in space?
Zero! that's why it is called zero gravity!
Does an object stay in place in zero gravity or does it rise?
In zero gravity, an object will typically stay in place if it is not acted upon by any external forces. If an external force is applied, the object may move in the direction of that force. Objects can float or move about freely in zero gravity depending on their initial state.
Which is more like sky zone or zero gravity?
zero gravity
When did you say that the zero gravity is no gravity?
Depends on the atmosphere. location, place, space and time of zero gravity
Why can liquids change their shape for example why can water flow?
Gravity causes water to flow downhill. A blob of water released inside a spacecraft under zero gravity, will form a floating sphere. On earth, If there are no sides to retain the water, the water spreads out and forms a puddle.
Is there zero gravity at the center of the earth?
Yes; the gravity from different sides should cancel, for a net result of zero gravity.
Is there such a thing a zero gravity?
No. Gravity is a force with unlimited reach. Gravitys grip-force decreases with an increase in the distance between bodies. In a nutshell, there is no zero gravity, but there is very close to zero gravity. In the deep space between and at extreme distances from any galaxies we find what is effectively zero gravity.
Where is the closest zero gravity place?
There is no "zero gravity" place. Gravity permeates all the universe. Astronauts in orbit are often said to be in zero gravity but they are, in reality, on a position where their orbital velocity balances the attraction of the Earth.
When was Zero Gravity Research Facility created?
Zero Gravity Research Facility was created in 1966.
