Why must a star convert helium after it has converted all of its hydrogen to helium?

Helium is the star's source of energy and if it has no energy the star would die.

What is Jupiter's minor gases?
The gases in Jupiter's atmosphere are hydrogen, helium, and methane.
What is the main gas in Jupiter's atmosphere?
The primarily element of Jupiter is hydrogen but a quarter of Jupiter's mass is helium. There must be some rocky core of heavier elements, but it is expected to be small. I am only in the 5th grade
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 is saturn's core and surface composition?
The atmosphere of Saturn (mostly hydrogen) increases in density, reaching a liquid, and finally a solid phase near the rocky planetary core (which cannot be directly observed). The atmosphere is very cold in the upper clouds, but the temperature increases sharply with increasing depth, reaching nearly 11,700° C at its deepest point.
How are scientists able to make predictions?
You assume that things that happened repeatedly in a certain way in the past will happen the same way under the same conditions in the future. If you throw a ball up in the air 500 times and it comes down 500 times, you then predict that if you throw a piano into the air it will come down as well. If you throw a helium balloon up in the air for the first time, you might predict it will also come down. When it does not, this means the theory must be rejected or changed to explain what is different this time. If you have a hydrogen balloon and throw it into the air, you might predict that since your helium balloon did not come down and hydrogen is more similar to helium than it is to a piano, then the hydrogen balloon will keep going as well.

Why is the presence of large amounts of helium in the spectrum of a star generally considered to be asign of age?
When stars form they are mostly made up of hydrogen. Main sequence stars derive their energy from converting hydrogen in helium in the cores. As the star ages the ration of helium to hydrogen increases. A star with a lot of helium there for must be old. When the hydrogen has exhausted in the core the star begins to collapse due to gravity until it reaches a point that the temperature of the core is sufficient to fuse Helium into Carbon.
Which organic compound contains carbon hydrogen oxygen nitrogen and phosphorus?
which of these elements must be in organic compuonds oxygen hydrogen carbon helium or iron
What condition must be in place in order for hydrogen to fuse into helium?
the temperature should be very high (around 107 K)
What materials could have been found in the giant cloud that formed the solar system?
More or less the same materials that are in the Solar System today - except that our Sun must already have converted a significant amount of hydrogen-1 to helium-4 in the meantime. So, the original materials must have been: mainly hydrogen-1, less hydrogen-2 (deuterium) and helium-4, and only fairly small amounts of the so-called "metals", i.e., any heavier elements. Of course, those heavier elements were essential in the formation of the Earth and hence the existence of life in the solar system.

Where does the sun get its hydrogen to burn?
You get hydrogen from water (u must have special kinds of machines to extract it from the water) or u can make it at home with a 1.5v battery....
Does non Muslim man need to do sunnat to get converted to Islam?
Yes, men and women must do sunna to convert to islam.
What is 1840 mL converted to L?
The prefix "milli", here abbreviated as "m", means 1/1000. Therefore, to convert from L to mL, you must multiply by 1000; whereas to convert from mL to L, you must divide by 1000.
Why does Hydrogen peroxide need to be broken down?
Hydrogen peroxide is a harmful by-product of many normal metabolic processes: to prevent damage, it must be quickly converted into other, less dangerous substances.
How were people converted into judaism?
The main requirement is the acceptance of Torah and the mitzvos (Torah-commands) with the intent to fulfill them. In addition, the convert must immerse in a mikvah (ritualarium), and men must be circumcised. People do not convert on their own; it must be under the aegis of a Rabbinical Beth Din.
