What else can I help you with?
I know that the Sun burns hydrogen to create helium but what is the Sun doing with all of this helium What would happen if the sun had no helium And what role does helium play in making the sun hot?
The Sun uses the energy produced from converting hydrogen into helium through nuclear fusion to generate heat and light. If the Sun had no helium, it wouldn't be able to sustain this fusion process, leading to a lack of energy production and a collapse in the Sun's structure. Helium plays a crucial role in the fusion reactions that occur in the Sun, contributing to the high temperatures and pressures required to sustain nuclear fusion.
What is the process that occurs in the Sun's core to produce so much energy?
Answer 1 The process that occurs in the Sun's core to produce so much energy is called nuclear fusion. Inside the Sun the temperature and pressure gets so high that substances fuse to from new substances. This process produces a large amount of heat, light and energy. Answer 2 Fusion. Isotopes of hydrogen bond together to form helium nuclei. Helium is a bit lighter than the hydrogen isotopes from which it is formed, and this difference, known as the mass defect, is matter converted into energy.
How does the Sun replenish its gases?
It doesn't. It is just so large that the gases will take a very long time to be "used up" in the fusion process that generates the Sun's energy output. A star is formed from a large volume of gas, almost entirely hydrogen. When the star's gravity brings this hydrogen to a sufficient density and temperature, fusion is initiated and continues until the star converts all of the hydrogen to helium, and all of the helium to even heavier elements. Our own Sun will take another 4 or 5 billion years to use up its hydrogen. It will become a "red giant" and eventually a smaller white dwarf star. At some point in larger stars, the energy from fusion reactions cannot support the weight of the gases, and a nova explosion results, throwing off matter or even disintegrating the star.
Why do all stars need Hydrogen and Helium?
Because without hydrogen and helium, stars wouldn't shine, not even the faintest stars! And plus if you mix them two together, there is a bang e.g helium balloon and and fire=BANG! Stars are made up of those two so that means they are a colossal fire ball, like the sun.Imagine it this way, a star was a massive helium balloon and someone got a fire burning stick and set it to this balloon, then there was a bang which is lasting millions of years!Eventually, the bang stops then this balloon explodes with energy and that's the end of that!

How does thermonuclear fusion contribute to the process of helium burning in a star?
Thermonuclear fusion in stars is the process where hydrogen atoms combine to form helium, releasing a lot of energy in the process. This fusion reaction is what powers the star and allows it to shine. In the process of helium burning, helium atoms fuse together to form heavier elements like carbon and oxygen. This process also releases energy and helps sustain the star's energy production.
How is a sun like star able to being helium fusion?

At what temperature do star begin the process of nuclear fusion?
Stars begin the process of nuclear fusion when their cores reach temperatures of around 10 million degrees Celsius. At this temperature, hydrogen atoms in the core of the star are able to overcome the electrostatic repulsion between positively charged protons and fuse together to form helium.
Why does nuclear fusion work inside the sun but not in jupiter?
Jupiter is not massive enough to create the high temperature and high pressure required by even deuterium-tritium thermonuclear fusion, the lowest temperature and pressure type of fusion. The Sun is much more massive and can fuse ordinary hydrogen, deuterium, tritium, and helium 3; producing helium. When the sun begins to run out of hydrogen in 6 billion years, the core will collapse and eventually be able to fuse helium into carbon and become a red giant. The red giant will swallow Mercury, Venus and Earth before it stops expanding.

Explain how the sun produse its energy?
The Sun is massive enough to compress hydrogen to a good density, and thick enough to retain heat for a good bit of time, so it is able to fuse hydrogen nucleii together to eventually form helium. This is where most of its heat / light comes from, gases heated by hydrogen fusion.
How does helium and hydrogen produce so much energy on the sun?
The cores of stars, such as our sun, have high enough temperatures and pressures to enable fusion of hydrogen nuclei - it is very difficult to fuse these positively charged particle together without these conditions. The mass of the nuclei before fusion is greater than the final mass of the fused particles - some of the mass is converted directly into energy through Einsteins equation E=mc2. m represents the mass, which although very small, is multiplied by the speed of light squared (c2), which is a very large number.
Which balanced equation represents a fusion reaction?
Deuterium (D) is a hydrogen isotope with one proton and one neutron. Tritium (T) is another hydrogen isotope with one proton and two neutrons. So when they combine, the result is D + T = He (Helium), which has two protons and two neutrons, + a free neutron. I can write this as D + T = He + n . Unfortunately WA does not have the tools to be able to write this in the usual physicists notation.
Does gravity make the sun's heat and light?
Yes. The sun is often cited as an example of energy from fusion of hydrogen atoms into helium. You might consider then that this is "simple" physical chemical reaction between these atoms. However hydrogen does not combine to make helium under normal conditions. What it takes is that the hydrogen atoms are squeezed together by the massive gravity of the sun until the nucleus of each atoms essentially touch and unite to form hydrogen and release energy in the process. In short the Sun is able to convert energy from gravity into light.

When the sun turns into a red giant and reaches the gas planets could it use them as fuel to keep burning?
No, the Sun would not be able to use gas planets as fuel to keep burning because the fusion processes that power stars occur in their cores, not on their surfaces. The gas giants, like Jupiter and Saturn, are primarily composed of hydrogen and helium gases, which are not suitable for sustaining nuclear fusion in the way that hydrogen is in the Sun's core.
