Question

How does the sun stay on fire in a place without any oxygen?

Answer 1

it isnt on fire

its a plasma.

cause by necular fusion && extremely high tempetures.

Answer 2

It's not "fire". Fire is cause by combustion.

The sun generates its heat via Fusion of two Hydrogen atoms to create a Helium atom. It does not require any oxygen, but it does require extremely high pressures - which is why fusion only occurs in the Sun's core (EXTREMELY dense).

Answer 3

Nuclear Fusion: combining Hydrogen to make Helium... its not fire (its heat energy) you can't put the sun out with 2 or 3 fire trucks...

Answer 4

Nuclear Fusion

Answer 5

It doesn't use oxygen for it's fusion process.

Answer 6

Well it looks like Sun is nothing but a ball of fire. But in reality it is not fire.

For most purposes there is no difference between a Fire and a star. Because both are similar. Both emit light. You could strike a match in dark and light that area, agree. So both make a dark area light. Both burn. Both generate heat. Both can damage nearby structures. Both can be contructive and promote and sustain life.

But strictly speaking they are different to some extent. Fire needs oxygen. A star doesn't need oxygen. It is a nuclear fusion process which liberates energy and that energy looks like fire. It has all the properties of fire.

Although the source of fire and star are different the actual composition of them may be similar. I do not know about that. After all what does a fire contain? what is the chemical composition of fire?  What a star produces and a burning wood produces are they same in composition??

Both look same, and both produce same effect including; light production, heat generation, both burn and damage bla bla.

So the composition may be same. But source is definitely different.  Also fire needs oxygen. Star no oxygen.

May be we can classify them as Star- Fire and Non star - Fire.

Both are a type of energy.

Answer 7

not on fire

Answer 8

The sun is not on fire, it burns through a chemical reaction.  This reaction is nuclear fusion, and it happens at the incredibly hot and dense center of the sun.  It is so dense there that it causes a cascade reaction where hydrogen atoms fuse into helium atoms, releasing a ton of energy.

Answer 9

Burning, or the combusiton of something is a chemical process of oxidation.  It does not transmute [change from one element into another] any atoms, it only affects the chemical bonds of molecules.

Every second, approximately 600 million tons of hydrogen is being turned into helium through the process of nuclear fusion in the center of the Sun.  It takes 4 hydrogen atoms to make on helium atom.  Here's the neat part.  4 hydrogen atoms contain more matter than one helium atom.  Where's the missing matter go? It was converted into energy.  What is the rate of conversion?  Everyone knows it; it's c squared.  As in E=mc^2 where E is the resulting energy, m is the initial matter and c is the speed of light.  This equation of Einstein's that everyone knows was proven through experiment by Lise Meitner and her research assistant [her nephew--sorry forgotten his name off the top of my head] shorty after Einstein published the General Theory.

Answer 10

Its not on fire.  It "burns", but that "burning" is caused by the fusion of hydrogen Nuclei into Helium and/or other heavier elements.  This is what causes the sun to give off light and heat.

Comparing the sun to a fire, however, is like comparing said fire to a hydrogen bomb: one will provide warmth and comfort, and the other will level a city.  After all, the sun isn't much more than a Large hydrogen bomb or a nuclear reactor

Answer 11

Very simple - its not on fire.

The sun produces light and heat from nuclear fusion at its core.  It is not burning as ordinary fire, so it doesn't require oxygen.

Answer 12

The sun is not on fire. It uses nuclear fusion to produce radiant energy and light. What looks like fire is actually light being emitted from the fusing of hydrogen nuclei.
