If the Sun is a big ball of fire and in space isn't any oxygen how can the fire burn there?

Answer 1

Its nuclear fusion that releases the heat, not burning a fuel in the presence of oxygen. Hydrogen atoms fuse into Helium and release loads of energy as radiant light and radiant heat.

Answer 2

The sun is a star. Stars aren't a big ball of fire. They're a big ball of hydrogen and helium. They "shine" because hydrogen combine to create helium, which in the process creates enourmous amounts of energy.

Answer 3

The sun is not a big ball of fire. Nobody has believed that for at least a hundred of years. It is a big thermonuclear reactor in space.

Answer 4

Yeps, it's nuclear fusion. The Sun is basically a giant ball of hydrogen. Because of it's giant mass, there exist gigantic levels of pressure in the core. This makes nuclear fusion of hydrogen atoms possible. The reaction results in energy and light. That's why the Sun is so bright ;)

Answer 5

The solar isn't hearth as all of us realize it. it truly is not flame. that's a nuclear reaction or technique. completely diverse. ben of marlow stated it suited, i think of ("it truly is simply by fact the solar isn't "burning" interior the actual experience. the approach that retains the solar going isn't combustion. it truly is nuclear fusion - the nuclear of Hydrogen nuclei into Helium. No oxygen is needed for this.")

Answer 6

The sun is a big ball of gas constantly engaged in one big chemical reaction. As all stars are. it won't last forever though. (I don't know how but....) Scientist have deduced that lifespan of a star the size of the Sun in about 15 Billion years. Earth is approx. 4.1 billion years old. So the Sun is about 1/3 dead.

Pretty cool huh?

Answer 7

It isn't a ball of fire. It's a great big thermonuclear reactor. The pressure of the fusing hydrogen and helium push outward but are largely held back by its enormous gravity.

Answer 8

its core is full of combustible materials - not all of them are known - the cores of suns burn for hundreds of thousands of our years or even millions. Picture a big blob of napalm - with plastics melted and combined - do you know how long plastic burns for? Its SUCKS the oxygen into it like a vacum - it has a massive vacume effect much more than anyone can imagine.

space is not sealed - so the oxygen is sucked and sucked and sucked - I suppose it is created and created and created from somewhere else in space

Answer 9

it is not exactly fire. it is heat energy. the hydrogen that makes up the sun fuses together in 10 millionC to form helium. the atoms lose some mass which is then turned into heat energy.

Answer 10

.o0o0o good question but the sun is just like a planet it has its own gravitation pull and atmosphere so therefore the sun does have some kind of oxygen around it.
