Why does a star's hydrogen supply run out?
A star's hydrogen supply runs out because of nuclear fusion in its core. As hydrogen is fused into heavier elements like helium, the star's core temperature increases, causing it to expand and cool. Eventually, the core runs out of hydrogen to fuse, leading to the star's evolution into a different phase.
What changing mass is the sun's supply of energy?
It converts Hydrogen to Helium by nuclear Fusion, eventually when hydrogen runs out it will convert helium to a heavier element and so on till it burns out and dies
Can Nuclear fusion solve our energy supply?
yes
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.
What percent of the US' energy does nuclear fusion supply?
The nuclear fusion is not used now as a source of energy; probable possible in a far future.
Explain the role of helium in stars?
Helium is an important element in stars as it is a byproduct of nuclear fusion, the process that powers a star. In the core of a star, hydrogen atoms fuse to form helium, releasing energy in the process. This energy generation is what allows stars to shine and sustain their existence.
What would be the advantages in using nuclear fusion to supply our energy needs in the future?
minecraft mine and CRAFT!
What process causes the Sun to continually burn?
The sun does not burn in the classical sense. The sun is so massive that, at its center, matter is compressed with such force hard that Hydrogen atoms fuse together to form Helium atoms. This fusion process liberates a great deal of energy, which escapes as light.
What type of stars are red giants?
These are stars that have exhausted their core's supply of hydrogen by switching to a thermonuclear fusion made of hydrogen in a shell that surrounds the core.
Environmental benefits associated with energy nuclear fusion?
Nuclear fusion produces energy without greenhouse gas emissions or long-lived radioactive waste. It has the potential to provide a virtually limitless supply of clean energy. Additionally, fusion reactions use hydrogen isotopes, which are readily available in seawater and do not pose the risks of nuclear proliferation associated with fission reactions.
A star the size of your Sun continues its fusion for approximately 10 billion years until the supply of hydrogen runs out The amount of hydrogen required to keep up that process indicates that?
Hydrogen is extreamly abundant.
What forces cause the expansion of the sun as it burns off its fuel?
The expansion of the Sun as it burns off its fuel is primarily driven by the balance between gravitational forces and the pressure generated by nuclear fusion in its core. As hydrogen is converted into helium through fusion, energy is released, creating outward pressure that counteracts gravitational collapse. Over time, as the hydrogen fuel diminishes, the core contracts and heats up, leading to increased fusion rates and causing the outer layers to expand. This process results in the Sun eventually becoming a red giant as it exhausts its hydrogen supply.
