Why is the sun slowly changing from being made of hydrogen to being made of Helium?

It is because of the nuclear fusion reactions which power the Sun. They produce
energy by converting hydrogen into helium.
In fact it's more complicated than the question suggests, but that's the basic idea.

What the core of the Sun made out of?
The sun consists of hydrogen and helium atoms. The hydrogen atoms combine in a process called nuclear fusion, releasing energy and creating helium atoms.
What substances make up most of the solar system?
That would be the hydrogen in the sun. The second most plentiful substancein the solar system would be the helium in the sun, being the fused hydrogen.
How does the sun get energy?
The sun is a hydrogen fusion machine. It forces atoms of hydrogen together to form helium. The slight economy of being in the helium atom format is released as energy which is released from the sun as light and heat. See Link
Where and when was the helium in the sun form?
The Sun consists of 70% hydrogen, 28% helium and 2% heavier elements such as carbon. Helium is being formed in the core of the Sun every moment of time. It has a hydrogen core and forms helium by nuclear fusion. The Sun is a "main-sequence star which means it stops after all of the hydrogen has been fused into helium. The hydrogen molecules collide rapidly, which causes the heat on the Sun, by atomic fusion, ever heard of an H-bomb? the Sun is a giant H-bomb but every moment has billions of explosions, due to the tremendous pressure of the core. giving it the ability to have solar winds, and high heat and light emission. A different type of star such as red giants will continue to fuse, which is how they become so large. After the hydrogen has formed helium, the outermost shell is hydrogen burning, with a helium fusing core, then carbon is formed in the core, pushing helium to the array of shells, still leaving hydrogen as the outermost shell. After the maximum amount of fusion occurs, there is a dense molten iron core, with silicon, magnesium, neon, oxygen, carbon, helium, then a hydrogen burning shell. Thats an entire lesson for you!
What inevitably forces a star like the Sun to evolve away from being a main sequence star?
Helium builds up in the core, while the hydrogen burning shell expands.
Why is the sun hotter than earth?
The Sun is hotter because it is made of hydrogen under high temperature and pressures that is being slowly converted to helium in a nuclear fusion process.
What fuel is being burned by main sequence stars?
Hydrogen is being "burned" into helium.
Is the sun made up of mostly hydrogen?
Essentially yes; the sun's energy comes from nuclear fusion with hydrogen being converted to helium.
What are the common elements present and their state of matter on Saturn?
The common elements of Saturn is Hydrogen and Helium. Saturn's powerful gravitational pull and atmospheric pressure allows Hydrogen and Helium to exist as a liquid around its core. In addition to being liquids most of its atmosphere is Hydrogen and Helium with Ammonia being the source of its yellow coloration.
What the core of the Sun made out of?
The sun consists of hydrogen and helium atoms. The hydrogen atoms combine in a process called nuclear fusion, releasing energy and creating helium atoms.
What is the two main gases on Saturn and their percentages?
Saturn is considered to be one of the "gas giants" of our solar system. The two primary gasses are Hydrogen and Helium.
What substances make up most of the solar system?
That would be the hydrogen in the sun. The second most plentiful substancein the solar system would be the helium in the sun, being the fused hydrogen.
How is a sun like star able to being helium fusion?
Hydrogen stalks run out
Which two chemical elements are being inter-converted in the sun?
The sun converts Hydrogen into Helium.
Why did the zeppelin company use hydrogen gas when helium gas would worked as well and been much safer?
During the time of the zeppelines, the US had more or less monopoly on Helium, and imposed an embargo on Germany on many things, one being Helium. The Hindenburg was designed for Helium, but had to turn to Hydrogen.
How are hydrogen and helium alike?
I'm fairly certain that both hydrogen and helium are lighter then air. Example, if you filled a balloon with either the balloon would float. And both are combustible. Hydrogen is some what more dramatic in its combustion however, the tragic example being the hindenburg.
What are the major and minor gases on neptune?
It not being certain of what amount or percentage is considered a "major" or "minor" gas, I have chosen to give the list of known gases in significant quantities: Hydrogen gas- 83% Helium gas- 15% Methane gas- 2%
