What happens to the liquid and gas particles placed in sun?
The liquid and gas particles in the sun undergo a process called "fusion." In fusion, atoms are melded together to create a larger atom. When this happens to small atoms (any atoms smaller than iron), there is a lot of energy released, which is why the sun is so bright and hot.
Explain How a main sequence star like the sun is able to remain stable?
The answer is "negative feedback", which is what provides stability in many other situations as well. In this case, if the fusion is too fast, the Sun gets hotter, expands... and the fusion gets slower. Similarly, if the fusion is too slow, the Sun will cool down, contract, and the fusion gets faster again. In summary, any deviation from a point of equilibrium will result in a tendency to go back to equilibrium.
How is a protostar different from a star?
A star begins its life as a ball of gas and dust. Gravity pulls the gas and dust into a spere. As the sphere becomes denser, it gets hotter and eventually reaches temperature of about 10,000,000 Celsius in its center. As hydrogen combines into helium, energy is released in a precess called neclear fusion.
The difference between a planet and star?
A planet is any collection of rock or gas that has enough gravity to pull itself into a spherical shape. A star is hundreds or thousands of times more massive than any given planet, and is a ball of plasma with nuclear fusion occuring at the core
Is iron the heaviest element made in abundance in massive stars?
Iron is the heaviest element made in the bowels of any star with the exception of a supernova explosion. All natural elements heavier than iron come from one of those.
What does an atom do if it colides with another atom?
Because atoms have negatively charged electrons orbiting the outside of them, atoms will repel each other. This means that it is extremely rare for atoms to collide, but when they do, the reaction depends on why it happened. If they are in a star for example, and the huge gravity and heat of the star forces them together, any atom lighter than iron will undergo fusion and make a heavier element. In fission reactors, it is extremely rare for an atom to hit another atom, but it can happen. Most of the time they will simply be hit by a flying electron before they can fuse, but even if they weren't, the atoms used in a fission reactor are much much heavier than iron and will not undergo fusion. The reason iron and anything heavier than iron cannot undergo fusion is that iron will absorb a huge amount of energy before it will fuse. In stars, the most powerful stable fusion reactors we know of, the iron will actually absorb so much energy that it kills the star. This is why stars will collapse after a short amount of time as a supernova. The supernova has layers with heavier and heavier atoms. When it reaches a layer with iron, it suddenly loses large amounts of energy and loses the ability to counteract gravity. This causes it to collapse into a dwarf star, or explode.
Where does nuclear fusion occur in any star?

What is a large ball of gas that emits energy produced by nuclear reactions in its interior?
when the supply of carbon is used up, other fusion reactions occur, until the core is filled with iron atom. +++ It is called a "star" - and it starts as hydrogen fusing to helium long before it forms carbon or iron. Iron is the end-product of medium-sized stars like our Sun.

What elements are formed during a nova or supernova?
It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.See periodic table (iron is number 26).See related link.
How do you define a star in astronomy?
A star is any hydrostatically stable plasma that generates heat and electromagnetic radiation by nuclear fusion.
Name one place where fusion happens naturally?
Any star, e.g. the sun.
What is a fusion reaction also known as?
Since they do not exist yet I do not believe they have any other names. Fusion does exist in nature so a sun or star could be considered a fusion reactor.
What is the only element that can theoretically release energy in neither fusion nor fission?
Iron... Iron has the lowest massper nuclear particle of all nuclei (elements) and can therefore not release any energy via either fusion or fission. ...home.sandiego.edu/~jhicks/lecture25/Lecture30.DOC
Does nuclear fusion occur in stars?
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
Is it possible for a comet with iron in it to pass through the sun's atmosphere and destroy it and how long would it take for the sun to be destroyed by it?
A comet would not have enough iron to affect the Sun in any measurable way. Even a Jupiter-sized planet made of iron would not stop solar activity. The production of iron by a star is an endothermic fusion reaction. Any mass of iron nearing the Sun would be vaporized, and whatever entered the solar interior would circulate for many hundreds of years before any could reach the core.
Why doesn't helium fusion occur at the surface?
Because fusion of any kind requires VERY high temperature and pressure, which can take place only in the core of a star.
