When the sun reaches its end all the hydorgen is converted into helium and when helium starts fusing again it converts into carbon and when 3 helium nuclei fuses it will result in oxygen. When all the helium gets converted into carbon and oxygen what happens to star after that. Will there be enough temperature to convert the carbon and oxygen? So what will be the fate of the star. Can i say that the star is completely dead after this?

When the helium is expended, carbon and oxygen start fusing into heavier elements. The process stops when iron-56 is reached, as the fabrication of elements heaver than that consumes rather than releasing energy. The result is an explosion, resulting in a white dwarf.

What makes your question so mundane is that our sun is essentially a somewhat boring star compared to others. A star nonetheless.
Helium is simply a gas. Fill a balloon with helium and when either released or escaped it will try to approach the sun. It probably won't make it, but it wasn't about the balloon in the first place. You can experiment all you like in our rather provincial atmosphere, the universe has a world of its own.
By the time you find someone who will (meaning can) tell you "what will be the fate of the star", you will be so close to heaven it won't even matter.

Yes, I would say that we call it a star because it has an ongoing fuel cycle, and that when the fuel cycle is done, you just have a huge mass of coal that only takes time to cool down. That is true for stars the size of our sun. Others may become neutron stars or go supernova. Our sun will probably become a red giant in its next phase and then cool off to cold. Great question.

Our Sun is estimated to be middleaged. What will eventually happen is the Sun will slowly increase in size and can reach as far as the Earth. This will take a very long time however and will get hotter before it begins to cool. Eventually it will shrink enough to be a quite a bit smaller than its current size.

It eventually dies, yes. When it reaches the point you mention, it's called a red giant.
We have many millions of years before our sun reaches that point in it's lifespan.
