What else can I help you with?
It takes an extremely high temperature for nuclear to occur inside the sun?
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.
How do you define a star in astronomy?
A star is any hydrostatically stable plasma that generates heat and electromagnetic radiation by nuclear fusion.
What makes nuclear fusion occur?
I found the website K1 Project very helpful. They had several articles underneath their Learn/Energy tab which should answer any questions about nuclear fusion.
Do any power plant today run run on nuclear fusion why or why not?
No, because the highest amount of energy needed in a nuclear fusion is 40,000,000 K, which is only known to occur on the sun.
Does nuclear fusion occur in stars?
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
Where does fusion reaction occur except from star and sun?
Fusion reactions can occur in laboratories through devices like tokamaks and inertial confinement fusion reactors. These devices use controlled conditions to generate the extreme temperatures and pressures needed for fusion to take place.
What re the phenomena involved about the sun?
Sun, you can say is a huge nuclear reactor in which a constant & rapid nuclear fusion takes place.Hydrogen is the basic constituent of any star which it use as a fuel for nuclear fusion to give higher elements with realease of energy due to mass defect. this, Fusion takes place all along the sun & hence enormous amount of energy is released.hence,nuclear fusion is the phenomena that keeps the star alive!
What do they use nuclear fusion for?
Nuclear fusion is not used for any purpose at present, it is still in the experimental phase
Why doesn't helium fusion occur at the surface?
Because fusion of any kind requires VERY high temperature and pressure, which can take place only in the core of a star.
Are there any known fusion reactions in the universe?
Definitely. Nuclear fusion is the source of all the light, heat, and other energy generated and radiated by every star you see, including the sun.
Does nuclear fusion occur at a low temperature?
No, normally it occurs at temperatures of millions of degrees. It does occur at room temperature, but not in significant amount; any possible practical use of "cold fusion" is, so far, speculation.
Can nuclear fusion continue indefinitely?
Nuclear fusion, like any process of producing power, uses fuel in doing so. In the stars, where fusion is the source of their energy, hydrogen is being used in fusion, producing helium plus energy. In any star the supply of hydrogen will eventually run out and the star will die, but its lifetime will be immensely long, many billions of years. On earth, if fusion can be made to work, it will use isotopes of hydrogen which are abundant, so as a source of energy it would last for many thousands of years.
