Why the sun is inexhaustible source of energy?
Technically the sun is exhaustible as it will eventually run out of hydrogen, but that is predicted to be 4-5 billion years in the future. Since the sun will be around for that long it is considered an inexhaustible source of energy.
What makes a fusion stop in the main sequence stage?
A fusion reactor stops in the main sequence stage when it runs out of hydrogen fuel at its core. As hydrogen is depleted, the fusion rate decreases, resulting in a decrease in energy production. At this point, the star will begin to expand and evolve into a different stage of its lifecycle.
What is a renewable energy resouce that is used to power the hubble space telescope?
HST runs on electricity supplied by massive Power Supply Units, which get their electricity from the 2 huge Solar Panels on either side of the spacecraft.
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.
The of the sun is the place that produces its huge supply of energy?
The core of the sun is the site of nuclear fusion reactions that generate its immense energy output. Temperatures in the core reach millions of degrees Celsius, allowing hydrogen atoms to merge and form helium, releasing vast amounts of energy in the process. This energy then radiates outwards towards the sun's surface and into space.
Can Nuclear fusion solve our energy supply?
yes
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.
What would be the advantages in using nuclear fusion to supply our energy needs in the future?
minecraft mine and CRAFT!
Is fusion reaction limitless?
Fusion reactions are not limitless. The fusion process can exhaust the supply of fuel and cause fusion to stop. Additionally, there are fusion processes that are not exothermic, but are endothermic and require energy to be put in to sustain them. Without the requisite input energy, fusion ceases.
Why the sun is inexhaustible source of energy?
Technically the sun is exhaustible as it will eventually run out of hydrogen, but that is predicted to be 4-5 billion years in the future. Since the sun will be around for that long it is considered an inexhaustible source of energy.
Why is sun fusion important?
Because it is the supply of energy that keeps us alive, and in fact makes the earth able to support life at all
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 is two advantages of using fusion as an energy source?
Two advantages of using fusion as an energy source are its abundant fuel supply (hydrogen isotopes) found in seawater and its low greenhouse gas emissions, making it a cleaner and more sustainable alternative to fossil fuels. Additionally, fusion reactions do not produce long-lived radioactive waste, minimizing environmental impact.
If nuclear fusion was possible how many KWH would it produce?
A nuclear fusion reaction has the potential to produce large amounts of energy, far exceeding current nuclear fission reactions. It is estimated that a single fusion reaction could potentially yield millions of kilowatt-hours of energy. However, practical implementation and scaling of fusion as a viable energy source on a commercial scale is still a significant challenge.
Hypothesize what will happen when the sun exhausts it's supply of hydrogen?
When a main sequence star, such as our sun, exhausts it's supply of Hydrogen, fusion of Hydrogen to Helium ceases in the core. This results in cooling of the core and therefore causes it to contract. As the core contracts, the layers surrounding the star gain kinetic energy until the fusion of Hydrogen is possible in the outer layers. As these layers undergo fusion, they increase in temperature dramatically. The outer layers expand due to heat, and the star becomes massive; the main sequence star has evolved into a red giant. Fusion of Hydrogen to Helium continues in the outer layers, whilst the fusion of heavier elements such as carbon occurs in 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.
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
