If fire feeds off of oxygen, what is keeping the sun ablaze?

Question

Fire is rapid oxidation. The sun is buring but there is no oxygen in space so what is keeping it going?

Answer 1

It is called fission reaction where hydrogen & its isotopes in high tempature produce helium. In this reaction a little mass converted in to energy as per E=MC2. So no oxygen is needed

Answer 2

The suns version of "warmth" ios like compaaring a marvelous, toasty fire to a hydrogen bomb. One will furnish heat temperature without delay, the different will produce immence warmth FROm leveling a city. merely placed, the solar is burning, yet unlike a hearth. interior the solar's middle, the solar has a insane volume of hydrogen. employing tactics on Nuclear Fusion, it fuses 2 hydrogen atoms right into a helium atom, making a plasma that provides off heal and lightweight. it extremely is using fact the suns middle is better than warm adequate to accomplish the reactions, considering that's over 15,000,000 ranges Celcius (over 27,000,000 ranges fahrenheit!!!!). hence, it may consistently fuse the atoms and supply off a sluggish furnish of sunshine, ability, and warmth. As for the oxygen question: there is unquestionably oxygen in area! the project is, no longer adequate to respire. Its almost like water in a sence: its there, yet we cant use it (In waters case, despite the fact that, its bonded with 2 hydrogen atoms, so its no longer a surprize we cant use it...) and hence, we arnt waiting to respire.

Answer 3

From Windows to the Universe:

"Fusion in the core of stars is reached when the density and temperature are high enough. There are different fusion cycles that occur in different phases of the life of a star. These different cycles make the different elements we know. The first fusion cycle is the fusion of Hydrogen into Helium. This is the stage that our Sun is in.

In stars with a very high temperature there are other fusion cycles that take place(CNO cycle). At higher temperatures, Helium burning produces Carbon. Finally, at even higher temperatures the heavier elements like Iron are formed. "

Answer 4

The sun's not "ablaze"; the energy released is from hydrogen converting to helium, which involves a reduction in the total mass of the sun according to Einstein's famous equation E=mc^2.

So, no fuel (as we think of it on earth) and no O2 = no oxidation or products of combustion.

Answer 5

Chandrasekhar had nothing to do with the hydrogen bomb and the sun was known to produce energy through fusion long before he was born. His work was in predicting the existence of degenerate matter in dead massive stars. Now known as neutron stars.

Answer 6

I cannot see why anyone would downrate TAXIRIDE's answer. It must be from someone who knows nothing about science. Fire is a chemical reaction and fusion is a thermonuclear reaction. Have you ever heard of the Hydrogen Bomb? Huge amounts of energy were released when it was denotated, and not because of fire either.

Answer 7

There are things other than oxygen that fuel the sun, like hydrogen and helium. the corona and blasts from he sun are plasma, an ionized gas, not flames.

Answer 8

Sun gets its energy by nuclear fusion which includes the combination of lighter nuclei to form heavier nuclei and the energy liberated results in light and heat. The more nuc fusion the more heavier the elements become finally resulting in Iron when the star looks red(red giant).........

Answer 9

Your mistake is SUN DOES NOT BURN its energy is nuclear by the Hidrogen

Answer 10

Hydrogen and helium
