Mr river tell this wise guys some solids are liquids .
Glass is not a liquid. Glass is an amorphous solid.
There is a lot of confusion around glass. There are even urban legends that very old glass windows are thicker at the bottom because the glass flowed over time. Not true at all.
I have a pretty good source of information, my wife is a glass technologist.
What did you got out of that with respect of that ? is glass liquid or solid ?
Glass is a solid at room temperature. The glass transition temperature or softening point of pure SiO2 glass is 2300 F.
I thought glass was a very viscous liquid . I know what glass transition temperature is I used to work with polymers and characterizing them and Tg. was one of the analysis, I am also somehow familiar on how to momowe the Tg. in polymers. Look guy I just wanted to throw a monkey wrench the argument " liquid "
Glass is an amorphous solid obviously.
Like river, do you also accept ghosts, goblins, Bigfoot, UFO's of Alien origins as fact?
Why?
If you were fair dinkum, why not accept the answer on its merits?
Don't bother answering. :shrug:

And SciAm has an (old) article on it:

That's fine, you just need to look somewhere else besides silica based glasses for your example. I am just supporting the wife's position.

What "argument "liquid""?
The issue that river cannot seem to grasp is that the liquid state is intrinsically a bulk property of an assembly of molecules, atoms or ions. The condensed states of matter (liquid and solid) only arise due to attractions between molecules, atoms or ion. Therefore, talking, as he or she has tried to do, about an isolated molecule, atom or ion being in the liquid state is quite meaningless.
Dave's posts, like mine in the old thread I linked to, have tried to address this point (though apparently without success, insofar as river's understanding of it is concerned). Your example of an amorphous solid like glass is not relevant to the point at all.
But, although your intervention was a red herring, the ensuing discussion has not been without interest. For example I thought the Wiki link, on how the glass transition temperature can be related to the transition in specific heat capacity, was interesting.

Oh ; I have grasp this concept of this " bulk " or a critical mass aggregate of water molecules in order to manifest ; this liquid called water.
But You have not grasped ; exchemist ; is the fact that ; in order to produce the whole ; a drop of water ; must be inside or outside each atom of H and O .
Since both atoms become a liquid at extremely low temps.
Now the challenge is to make each atom of both H And O do so , individually .

How exacly does an atom become a liquid?
Thats the question . that is the essense of my investigation . and that investigation will bring forth knowledge .
Doesn't ?
The aggregate is the manifestion of the individual atom. And what it is doing.
