Helium ash is merely helium. Helium is commonly referred to as ash in discussions of our sun's fuel (and others stars of similar size/composition) to indicate that it cannot burn (or really cannot be fused into a larger atomic element). Our sun fuses hydrogen into helium at its core but the temperatures and pressures are not high enough to fuse helium, so it is called ash. If the core had a higher temperature/pressure, the helium would be fused into a larger element (carbon), something that happens with more massive stars. In such a star it would not be called ash because the conditions would be such that it could be fused ("burned"), so it would merely be called helium.
What else can I help you with?
A large bright star whose hot core has used most of its hydrogen is a?
Red giant. The word "most" in the question isn't quite accurate. There is still a lot of hydrogen remaining in a star when the amount of helium becomes a problem. Hydrogen in the star is fused into helium, and the helium is at least roughly analogous to the ash in a wood fire; it is what's left over from the hydrogen fusion, and too much gets in the way. When the proportion of helium gets too high - above about 50% is enough - the helium begins to interfere with the hydrogen fusion process. Without enough new heat generated by fusion, the star begins to collapse under the influence of gravity. The compression increases the temperature, and when the pressure and temperature gets high enough, the helium "ash" in the core becomes helium "fuel" for the Red Giant phase.
What elements are formed by stars less massive than your sun?
Stars less massive than the Sun primarily fuse hydrogen into helium in their cores. This process releases energy and creates elements up to helium. These stars do not have enough mass to create heavier elements through nuclear fusion processes.
How much can a helium balloon lift?
depends how big the helium balloon is and how many
Does helium have a lot of pressure?
yes helium does have a lot of pressure.
Gas giants have atmospheres composed primarily of helium and what?
Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.
Could you die from helium?
Not exactly. Helium is an inert gas, and is not toxic.However, you could die from not having oxygen, so if you breathe only helium, yes you could die.
Why didn't Ash's Charizard obey Ash?
Im not exactly sure, but I think its because Mewtwo insulted him by saying he was poorly trained, so he listened to Ash to prove Mewtwo wrong
What does a star do for 90 percent of its life?
For about 90% of a star's existence, it fuses hydrogen into helium, producing lots of heat. When the hydrogen starts to become depleted and the helium "ash" starts building up, the star may expand into a red giant, in which it fuses helium into carbon and heavier elements.
Why would an older main sequense star be composed of a higher percentage of helium than a young main sequence star?
A star's nuclear fusion reaction converts hydrogen into helium, and generates energy through this process. A "new" star has a fairly low percentage of helium, but over the course of billions of years, it fuses the hydrogen "fuel" into helium "ash".
Do episcopalians put ashes on their foreheads on Ash Wednesday?
No, because Ash Wednesday as we now know it did not exist then.
Do Pokemon get sick?
Of corse they do! Remember in the movie ''Lucario and the Mystery of Mew'' how Mew got sick? Exactly. And in Pokemon HeartGold Version when you have to help out that lighthouse Ampharos? Exactly. And when Ash threw up in Pikachu's face? Exactly.
What is a scientific question for helium?
How exactly stars make helium out of hydrogen. We know it happens but it still has some mystery to it. The number of neutrinos emitted does not seem right.
What has the author David W Graham written?
David W. Graham has written: 'Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic' -- subject(s): Isotopes, Isotope geology, Volcanism, Lead, Helium, Volcanic ash, tuff
What episodes of Pokemon does a Pokemon sleep on another Pokemon's belly?
i cant say which exactly but it when ash has snorlax and all the pokemon are sleeping on him
Does a mole of carbon atoms have three times greater then helium?
No, a mole of carbon atoms has the same number of atoms as a mole of helium atoms (Avogadro's number, which is about 6.022 x 10^23 atoms). The difference lies in their atomic masses, as carbon atoms are heavier than helium atoms.
Can you give adult rabbit a shower?
No. the rabbit should only be "washed" in a special ash. the ash dosen't interfere with there oils.i cant tell you exactly where to get it, but you can. just go to a pet store and ask. im sure that they will have it. Hope this helps!
Which pokemon did ash catch first?
Pikachu, He didnt exactly catch Pikachu it was given to him by Professor Oak. The first pokemon he caught was Caterpie
