This is kind of stupid to ask  
Matter exist in 3 states : solid , liquid , gas
So can oxygen exist in solid form at a very very low temperature ??

[Mitch]

Good Question, I actually don't know. Hmmm.... I wonder if webelements would have the answer.

[Mitch]

Webelements says that solid Oxygen forms at 54.8K or -218.3 °C or-360.9 °F

[Julie]

Wow ...
So other gases may also be in solid form at a very low teperature ?  

[Mitch]

Yeah strange huh. Gregpawin recently told me that liquid helium is so weird that if you had it in a beaker it would climb up the walls and out of the beaker

You can go bug him with strange questions like that in the Physical Chemistry board he moderates.

[Julie]

I wonder how cute will oxygen be in solid form ... lol  
Liquid Helium will "climb" out of the beaker It's really weird indeed !!

[Seymor-Omnis]

I guess the "climbing" makes sense though, since hydrogen has a lower density than oxygen, i think...

[jdurg]

Yeah.  Apparantly liquid Helium disobeys many laws of physics as it really does not experience friction with other surfaces.  I wonder what color solid oxygen would be?  I'm guessing that it would be a bluish semi-metallic like substance due to it's location on the periodic table and the fact that liquid oxygen is blue.  (Liquid oxygen is really fun, but dangerous, to play with).  I know that liquid O₂ is attracted to a magnet, and that it will condense on the outside of a metal container holding liquid nitrogen.  

I know that in recent years solid hydrogen was formed and it was found to be a metal.  Solid helium may be a bit tough to come by as it melts at about a degree above absolute zero.

I was chating with my friend and I asked her about this question : Can oxygen turns to solid at low temperature ?
She said gas is compressed to turn to liquid ...
So when liquid is being compressed ... I guess it will turns to solid ...  
Liquid oxygen is blue ...This picture is from Webelement

Don't forget that 4th state of matter: plasma.

For a great look at liquid oxygen in action, check out the mirrors of George Gobel's old homepage from Purdue.  He burns 40 lbs of charcoal in 7 seconds with liquid oxygen.

And, yes, you can make lots of elements in solid form with low enough temperatures.  The really amusing one is argon--it's only got a few degrees of liquid range and I freeze it solid all the time in my liquid nitrogen trap.  Kind of funny to watch it melt and subsequently boil away, all well below freezing.

Packing of solid oxygen in unit cell - space group C2/m, bond length in Angstrems.

Solid oxygen definately DOES exist, I was having a discussion some time ago on the properties of a weird green allotrope of phosphorus that apparently has properties similar to solid O2,
and as far as I know helium is the ONLY element that cannot be turned into a solid be ANY temperatures possible with todays technology, I imagine solid oxygen would be a pretty damn powerful oxidizer, and solid O3 to be absolutely obscene in it's oxidizing power

[AWK]

All gases, even helium can ne solidified.

[Limpet Chicken]

Helium may in theory be able to be solidified, but I really don't think it has, or indeed CAN be done with todays technology, scientists have supercooled it down to a few billionths of a kelvin, and it still hasn't solidified, but it would be interesting to see what properties solid helium has,  I bet it would be one of the best superconductors known to man  

[AWK]

any gas can be solidified, even helium.
