are stars mostly made of solids liquids, or gases?

Answer 1

There are four basic states of matter: Solid, liquid, gaseous, and plasma.
http://en.wikipedia.org/wiki/State_of_matter

Most of the Sun is a high energy Plasma... basically a soup of protons, neutrons and electrons being constantly shuffled around.

To quote one source: "In physics and chemistry, a plasma is typically an ionized gas, and is Usually Considered to be a distinct state of matter in contrast to gases because of its unique properties." (source - The Plasma Physics Wiki: http://en.wikipedia.org/wiki/Plasma_%28physics%29 )

The majority of the Sun's composition is made up of Hydrogen and Helium in these proportions:
Hydrogen 73.46 %
Helium 24.85 %
(the remainder are trace elements)

The rest of this is probably more than you really wanted to know but I couldn't help myself :)

The Sun (or any other star) has structure.

There is a Core where the majority of the heat is generated via fusion of hydrogen into helium. The Core has a density of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is close to 5,785 kelvins (1/2350th of the core)). Through most of the Sun's life, energy is produced by nuclear fusion through a series of steps called the p-p (proton-proton) chain; this process converts hydrogen into helium

There is a Radiation Zone where the intense heat of the core is transmitted outward.

There is a Convection Zone where the heated plasma from below is circulated to the photosphere where it cools and falls back to be reheated.

Then there's the Photosphere... the visible surface of the Sun.

Next is the Atmosphere... which is comprised of five principal zones: the temperature minimum, the chromosphere, the transition region, the corona, and the heliosphere. The heliosphere, which may be considered the tenuous outer atmosphere of the Sun, extends outward past the orbit of Pluto to the heliopause, where it forms a sharp shock front boundary with the interstellar medium. The chromosphere, transition region, and corona are much hotter than the surface of the Sun; the reason why is not yet known.

Hope this helps!

Answer 2

Stars are mostly made of Hydrogen. Hydrogen is the fuel for all the stars. At the core of stars, hydrogen atoms combine to form helium and release energy which is called as "nuclear fusion". At these high pressure and temperature different elements are created as the time goes. As the time goes the hydrogen gets exhausted and finally depending the size of the star , either it becomes a white dwarf ( our sun will become white dwarf ) or a black hole ( if star has to be a black at its end it should have around 10 times the mass of sun )

Answer 3

None of the above. Stars are made up of a substance called plasma, which is higher in energy than even gases.

Answer 4

None of the above. There are two other states of matter you're forgetting, and one of them is plasma, the main component of stars. Also some gases, but almost all plasma.

Answer 5

the sun is so hot, that many of the things the sun is made of, get so hot that solids get melted into molten liquids, and liquids are boiled into a gas.
and yet, the sun is only a middle aged star, it is of average temperature.
the last time i looked into it, the ingredients of the core of the sun were still under debate. i read somewhere, someone was saying it was nickle, and another person was saying it was something else. how would you go about finding out what the middle of something that hot was made out of?

Answer 6

Stars are made of what is called 'plasma'. But, at the core of a star, the pressure on the plasma is so great that it's density is greater than that of any solid.

Answer 7

The sun, and all luminous stars are gaseous. Plasma, mentioned above, is very hot gas, but still gas.

Answer 8

Stars are made from the gas Hydrogen and the burn it using fussion and turn it Helium I beleive.

Answer 9

Because of the temperature stars can only be gaseous for the most part.
