.euphoria said:You need to add in several factors here my friend! Factors such as;
Does this star have a planet system?
How big of a star are we talking?
Are tidal forces at play?
But let's put those factors aside for while. I'm assuming this star doesn't have a planet system. So yes in the strange scenario, I suppose the outer layers would most likely freeze over due to the phenomenal outside temperatures of outer space. But most likely the inner layers would still stay liquid.
Depending upon the size of your star and mass, I suppose the inner layers would become some form of metallic liquid. I could imagine.
In fact, The star would probably never ever produce any form of H2O as hydrogen nuclei fuse with each other to produce Helium. As this hydrogen is depleted, The star creates another denser layer on the inside and pushes out the hydrogen fusing layer. So now the star is fusing heavier nuclei together and so the process goes on.
Hope I helped some how, If I am wrong in anything i stated please do feel free to correct me. :)

Danger said:I can't provide specific time-lines, but I rather suspect that there wouldn't be much hydrogen left in the area by the time oxygen shows up. Stars don't fuse everything at once. When the initial hydrogen-to-helium2 tapers off, the radiation pressure can't maintain itself against gravity, and the star collapses a bit. That compression allows the helium2 and remaining hydrogen to combine into helium3. The next stage is lithium, then carbon (beryllium and boron are in there too, but not really important). After carbon comes oxygen, by which time pretty much all of the hydrogen is gone. Remember also that at stellar temperatures the substances are in plasma form rather than gaseous, so molecular bonding can't occur. Fusion is the only way that atoms can combine, since all of the electrons are stripped off and flying around loose.

NobodySpecial said:The middle would get quite hot just from the energy of gravitational collapse, probably enough to keep the surface liquid.
Although space is cold water has a large heat capacity so it would take a lot to freeze it, even with the low vapour pressure of a vacuum it would take a long time to evaporate.
The gas giants, or at least jupiter, has a significant heat output just from the gravitational energy of it's own mass.
Danger said:You can't just randomly say that. It's physically impossible, so what's the point of fantasizing?
Mortalitis, where did you ever get the idea that fusion occurs in Earth's core? The Earth's internal temperature comes from the decay of radioisotopes. Jupiter is the closest thing to a protostar that we have, and even its humongous gravity isn't enough to initiate fusion.
I seriously recommend that you abandon whatever source you have been receiving your science education from and hang out here a lot more.
The sun turning completely to water is a hypothetical scenario and not scientifically possible. The sun is a massive ball of gas, primarily made up of hydrogen and helium, and it is held together by its own gravity. It cannot simply transform into a liquid state.
If we assume that the sun somehow turned into water, it would likely be in a gaseous state due to the extreme temperatures and pressures within the sun. The water molecules would be constantly colliding and breaking apart, creating a superheated gas.
If the sun turned completely to water, it would likely not freeze or boil. The temperature and pressure within the sun are far beyond the freezing and boiling points of water. However, if the sun were to suddenly cool down or expand, then it could potentially freeze or boil.
If the sun were to turn into water, life on Earth would cease to exist. The sun is crucial for sustaining life on our planet, providing heat and light for photosynthesis, among other essential processes. Without the sun, Earth would become a cold, dark, and uninhabitable planet.
No, it is not possible for the sun to turn into water in the future. The sun is constantly undergoing nuclear fusion, which is the process of converting hydrogen into helium. This process will continue for billions of years until the sun eventually runs out of hydrogen and dies, but it will never turn into water.
