If fire needs oxygen to burn then how do stars burn in space where there is no oxygen ?

Answer 1

Stars don't burn. It's called fusion.

Burning is a chemical reaction that requires oxygen. Fusion is a when multiple atomic particles join together to form a heavier nucleus and release energy.

Answer 2

Stars do not "burn". Nuclear Fusion takes place in stars. This is the same as a hydrogen bomb going off. No oxygen is needed.

Answer 3

Stars don't burn in that they do not get their energy from chemical combustion. Even if you could get a mass of coal as big as the Sun together and ignited it, it would last only a few thousand years. Stars get their energy from nuclear fusion, where light atomic nuclei are joined toghether into heavier ones under enourmous heat and pressure. In the process, vast amounts of energy are released in the form of heat and high energy gamma rays under Einstein's famous E=mc2 equation. In this way a star can shine for billions of years or even longer. The lighter nuclei are just a little heavier than the larger ones that are formed by nuclear fusion, and the tiny difference in mass is radiated away as energy. A star like the Sun converts 650 million tons of hydrogen into helium each second, with 4 million tons being turned into energy that makes it shine and keeps us alive on Earth. The burning astronomers refer to is not combustion, it's the production of internal nuclear energy through the conversion of lighter elements into heavier ones.

Answer 4

Stars Don't Burn They Emit Their Energy By Using Hydrogen And Helium.

Answer 5

Hello Doc...

Ah - small correction here...stars are not burning as in FIRE.
They are giving off heat, light, and radiation from the Nuclear Fusion going on within them that is converting Hydrogen Gas into Helium Gas as a result of the enormous pressure and heat of the huge mass of gas pressing down on the central core of the star. surface temperatures on Stars is around 10,000 degrees F. Core temperatures are in the range of millions of degrees F. to give you an idea of the temperatures involved.

The nuclear reactions involved might be likened to the same thing going on within a nuclear power plant (on a very small scale).

Answer 6

Because stars dont burn oxygen. Most stars depending on their stage being by burning hydrogen. Fire can be created by oxygen but the reaction stars create by burning hydrogen and by doing that they create iron, which they burn later on when they run out of hydrogen. Basically a star makes a run through the periodic table of elements before killing itself...lol

Answer 7

The solar can "burn" hydrogen to helium devoid of the opt for for oxygen. The solar would burn hydrogen to helium by ability of making use of the C, N and O as catalysts. Even in those stars, notwithstanding, a loss of oxygen does not ward off nuclear burning. study up on your data first earlier you pass on an anti semetic tirade.

Answer 8

Um.... stars don't need oxygen, because there's no chemical burning occuring - they're fusing. Most are fusing hydrogen atoms into helium atoms, but there are more massive stars that fuse heavier elements.

Answer 9

STARS---DO---NOT---BURN!!!!!!
Burning is a process of oxidation. Stars are undergoing fusion. Fusion is a nuclear process, burning a chemical process. HUGE difference.

Answer 10

I was going to say the same thing, about nuclear fusion, but someone's already said it
