Stars are formed as a result of a large cloud of gas and dust coming together to form a nebula. As additional particles combine with the nebula, it's gravitational force increases. This increase in gravitational force pulls the particles closer together, and as the particles are pulled closer together, the temperature inside the nebula increases. (It is known that the center of the earth is a hot matter, probably molten liquid. This is caused by the tremendous pressure and resulting heat in the center of the earth as well as the gravitational pull.) Stars are much larger than the earth so the gravity is significantly greater and more pressure is generated. This enormous pressure results in very high temperatures being generated. When the center of a nebula reaches a temperature of 10 million Kelvin (10,000,000K), fusion begins. The fusion reaction releases energy and a star is born.
When the sun was created, it was a ball of helium. It then grew so hot, the atoms of helium started to fuse. All stars do this to maintain 'life'. As the star fuses these helium atoms, they form hydrogen atoms, which are heavier. This is the main part of their lifespan. Then, when they start to die, they have run out of helium and start fusing hydrogen, which causes them to expand. Then, they eventually die. Our sun will live through a couple more billion years before reaching this stage.
Nuclear Fusion tkaes place and the sun is hot.
it happens when two stars love each other very much and then magically pops out a nuclear fusion
around 10 million degrees Kelvin
Nuclear fusion is the process that powers stars, such as our sun.
No, while it is hot enough the pressure is too low.
Nuclear fusion. A by-product of nuclear fusion is energy given off, that we see as visible light.
Fusion. Apex
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
yes nuclear fusion does occur on the sun, creating intense heat and light
Sun
Nuclear fusion is the process that powers stars, such as our sun.
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
High temp and pressure
Nuclear fusion; hydrogen into helium.
It has to be at hundreds of millions of degrees kelvin, before a fusion reaction between deuterium and tritium will start
The rest of the sun is too cold and too low pressure.
No, while it is hot enough the pressure is too low.
Nuclear fusion. A by-product of nuclear fusion is energy given off, that we see as visible light.
The energy which produces light and heat in the Sun comes from "nuclear fusion" deep inside the Sun.
