When the sun exhausts its hydrogen fuel in about 5 billion years, it will begin to fuse helium into heavier elements like carbon and oxygen. This process occurs during the red giant phase, where the sun will expand significantly. Eventually, after burning helium, the sun will shed its outer layers, leaving behind a hot core that becomes a white dwarf, marking the end of its nuclear fusion processes.
What else can I help you with?
Why sun have hydrogen and helium?
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
The sun will eventually use up its hydrogen fuel and become what?
The sun will eventually exhaust its hydrogen fuel and will undergo a transformation into a red giant star. This will happen in about 5 billion years. After that, it will shed its outer layers and become a white dwarf.
Why does the sun always burn and not go out?
The sun burns continuously due to nuclear fusion in its core, where hydrogen atoms fuse to form helium, releasing a huge amount of energy in the process. This process produces the heat and light that we receive from the sun. As long as there is enough hydrogen fuel in the sun's core, it will continue to burn and emit energy.
How does fuel in the sun keep refueling itself?
The Sun does refuel itself, in a way. When the nuclear fusion in the Sun converts its stock of hydrogen into helium, the hydrogen amount is gradually decreasing. The Sun will continue to burn hydrogen as it has since about 4.6 billion years ago, then it will use the helium. There are other nuclear reactions possible after that. At each stage the Sun will use elements created by itself to produce more energy. But eventually the Sun will become a red giant star.It will finish up as a white dwarf star with no fuel left. It will not become a supernova.The question asks about the Sun refueling by itself, and its main fuel is Hydrogen When it will finish, any other nuclear reaction will represent nothing as a source of energy to the Earth. The unique nuclear reaction that interest to the life on the Earth is that provided by Hydrogen, which represent a huge amount of energy released every second on the form of a nuclear fusion So, the Sun doesn't refuel itself on the sense that more Hydrogen is added. About the Sun becoming a supernova I was wrong.Edit: Any mass in outer space acts like a gravity well, I still stand on my answer to the Hydrogen particulates in space [Like A blue Whale eating krill] that is endlessly refuelling the Sun, Helium conversion seams to me to be some sort of balanced counter measure to keep the Sun in it's current consistency. Like how to cool down a furnace without turning off the flame? Switching to a less intense fuel, like Helium instead of Hydrogen. Firewood = Hydrogen, Kindle = Helium. Large as the Sun is... it would have already converted [burned up all the Hydrogen to Helium] far back then and note Scientists factoid our Sun as a small one. Hence an outside supply must be in play for the consistency to keep hands down.
What fuel did the Apollo 15 use?
The fuel used by the Apollo 15 spacecraft as well as all the Apollo spacecrafts , was a mixture of oxygen and nitrogen gases.
Why sun have hydrogen and helium?
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
Does energy used by fuel cells come from the sun?
Yes, the energy used by fuel cells can ultimately be traced back to the sun, especially when the hydrogen used in fuel cells is produced through renewable methods like electrolysis powered by solar energy. In this process, solar energy is converted into electricity, which splits water into hydrogen and oxygen. This hydrogen can then be used in fuel cells to generate electricity. Therefore, while fuel cells themselves do not directly use sunlight, their energy source can be solar-based.
How does the sun use up its fuel?
All stars- including our sun- are an ongoing nuclear fusion reaction- hydrogen is fused into helium. The hydrogen is consumed in that reaction.
The sun will eventually use up its hydrogen fuel and become what?
The sun will eventually exhaust its hydrogen fuel and will undergo a transformation into a red giant star. This will happen in about 5 billion years. After that, it will shed its outer layers and become a white dwarf.
Can you use hydrogen peroxyde in a fuel cell?
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
Fuel-cell automobiles use gas as a fuel?
No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
What kind of fuel did the saturn v use?
It used liquid oxygen and liquid hydrogen.
How is proxima centauri similar and different from the sun?
Proxima Centauri is a "red dwarf" star. Its composition is similar to the Sun, but with less mass and it's much smaller than the Sun. It has lower core and surface temperatures. The Sun will eventually start to use helium as well as hydrogen as its fuel It will become a red giant then a white dwarf. Red dwarfs don't have a high enough core temperature to use helium as as "fuel". Proxima Centauri will not become a red giant. It will go straight to the white dwarf stage, once it has used up its hydrogen "fuel".
In a rocket what fuel do they use?
They use hydrogen
How to use hydrogen fuel for two wheeler motorcycle?
You can use the hydrogen in fuel cells for power generation for a two wheeler motorcycle.
Does hydrogen use a fuel cell?
yes it type of fuel
What is the fuel that is used for cell activity?
Water and they also use gas. They use a hydrogen cell, which explains the need for water.
