what causes the sun to burn?

Question

fire needs oxygen, so where is the oxygen coming from,when theres none in outer space.whats fueling the sun?

Answer 1

Nuclear reaction and something to do with magnitsim that causes a feedback loop and keeps the reaction going. I think its the same thing that keeps the earths core molten and burning and moving.

Answer 2

You are confusing chemical reactions with nuclear transformations. According to Einstein's famous equation that produced the atomic bomb; E=mC^2; a small amount of mass (m) is converted into a large amount of energy (E) using the constant, the square of the velocity of light (C^2). In this instance four hydrogen atoms are combined into one helium atom, and in the process a tiny amount of mass is changed into energy. This is a simplistic view of what really happens in the sun, and it really doesn't happen like this, but the end result is that mass is converted into energy with using any chemical methods.

Answer 3

the sun's centre is made up of hundreds of gases which cause nuclear reactions. and there isn't any oxygen there's alot of hydrogen which burns profusely inside the suns core therefore causing the reactions which create heat,light and a hell of alot of energy. u see bertucus is right but there is no loop the sun's life it's just simply burning up all its fuel i mean its allready 5.6 billion years old maybe even older.

Answer 4

The immense gravity of the sun causes two atoms of hydrogen to fission into one of helium giving off radiation as a by-product. It is the radiation that heats the sun and eveything within millions of miles.

Answer 5

it particularly is a thermal burn, in basic terms like various different from the warmth. because of the fact of this human beings could positioned on protecting clothing and sunscreen while going out in the solar ( even whether that is not genuine warm exterior). it particularly is an genuinely burn to the exterior, and can reason injury.it is likewise achievable to get a burn from being out in the wind.

Answer 6

Energy is produced by exothermic thermonuclear reactions (nuclear fusion) that mainly convert hydrogen into helium.
Sun produces an appreciable amount of heat via fusion
About 3.6 ×1038 protons (hydrogen nuclei) are converted into helium nuclei every second, releasing energy at the matter-energy conversion rate of 4.3 million tonnes per second, 380 yottawatts (3.8 ×1026 W) or 9.1 ×1010 megatons of TNT per second. The fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos, and energy. .the proton-proton chain dominates.
fusion does'nt require oxygen

Answer 7

The sun is not burning. The reaction on the sun is a nuclear reaction, fusion of hydrogen into helium.

Answer 8

The sun isn't burning. The energy is caused by a nuclear reaction in its core

Answer 9

The sun is a nuclear furnace converting hydrogen atoms into helium atoms and producing radiant heat.

Answer 10

well im no genius so all i have to contribute is..gases maybe?...and this is off topic but im all paranoid about us colliding with it or chunks of it flying at us.
