We know that fire requires oxygen for its combustion but how do sun is still full of fire without existence of oxygen in space???
Answers
The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. ... Hydrogen really doesn't burn, it fuses, into helium. So no oxygen is required!...
Hope this helped....
Explanation:
♡ ↪It could also burn in the presence of flourine, or chlorine, or bromine, or well, quite a list of other “oxidizing agents” (which, oddly, do not for the most part contain oxygen)
But “burning” is “combining with an oxidizing agent” and given the absence of that in any bulk… ok, another caveat, there’s actually quite a lot of oxygen in the Sun. Turns out that’s one of the most common elements in space, and the Sun, being a big gravity well, has quite a lot of it gathered together. And its… well more on the “and it’s…” part later. Anyway, it’s just that there’s a lot more hydrogen and helium there than oxygen, vastly more, and we can ignore the oxygen for the moment.
Because,,The Sun isn’t burning.
Sun isn’t burning.I know, you’re used to seeing a light source and thinking “well, that’s fire”
But you aren’t really, are you? Because you see light bulbs all the time, and they, at least older ones, glow brightly because they have a little spring inside which has been heated to high temperatures in a vacuum.. deliberately in a vacuum because that means, as you’ve already pointed out, they won’t burn.Things emit light because they are hot, not because they are on fire. Fire is just a way to make things get hot. But electricity will work too. If you have an electric stove, or a toaster, you can watch this work as well, notice that the elements start to glow when they get hot. Again, they aren’t on fire, they’re just really hot, so they are radiating visible light.
