Glass, solid or liquid??

bitemybanger

Did you know that glass, at standard temperature and pressure, is a liquid? Glass looks and acts like a solid, doesn't it. But it is a liquid. Or is it?

Dr.Louis

i know- its freaky... they call it a 'super cool' liquid.

its the reason why old windows get kind of warped at the bottom, over time the liquid is moving down...

I remember a sad crowd of UCD chemistry students coming into my primary school and claiming this. Whether or not I believe them is another matter. As far as I know it is considered a liquid however.

I believe it is a liquid. Panes of glass in really old (like 80+ years) actually look like they're pouring. The glass pools at the bottom of the pane.

Someone with technical knowledge will prove me wrong in a moment, but I believe its true. ITS A LIQUID!!!

Also, poo is a solid!!

It flows out your ass like a liquid (except when you have to pry it out with your fingers:(), but scientists classify faecal matter as a solid.

Amazing stuff. Go AH!!

bleg

it's an amorphous solid

Terry

Isn't glass made from sand and isn't sand a solid?

I know that glass is a liquid, but it's made from a solid, so something is amiss somewhere alond the line.

Wrong,

urban myth.

Old glass was often uneven, and a non thick glazer would put the thick part at the bottom.

A thick glazer sometime put the heavy part at the top < flowing up?

Glass is an amorphous solid.

http://en.wikipedia.org/wiki/Glass#The_physics_of_glass Look at the antique glass making techniques.

If you fell of a 50 foot cliff into water, im sure it would feel solid too

Glass is a type of non-crystalline or amorphous solid.

Glass is surely a crystaline solid. edit: Sorry amorphous solid

Old glass actually always was uneven as it was poured rather than extruded as it is today.

Glass is glass, why complicate things with your vodoo talk.

And spun to stretch it, leaving thick edges.

Just to be different I'm going to say it's a gas.

how is it made from a solid but a liquid all at the same time. jaysus the world is a mad place.

Hagar

Liquid, same as asphalt.

Next people will be saying carbon is a metal

im_invisible

sure water is made of two gasses, and its a liquid, and if you throw it in the freezer, it turns into a solid

zuutroy

now..everyone go and mix some cornflour with water to form a non-newtonian fluid...then you'll be really confused

No, water is water. In it's frozen form we refer to it as ice, in its liquid we call it water & when boiled it's steam

Yeah, but the point is whether something is a liquid or a solid or a gas is usually dependent on the temperature. It was just to point out that substances can easily change state, it's not so confusing that glass is made from sand.

Interestingly enough, the glass casing for this experiment hasn't started dripping yet

...and that's all relative to ambient temperature and pressure. The molecule remains the same, it's just that it's environment determines how those molecules and the atoms making them up behave.
If we were to think along these lines then every single element, compound and alloy could be said to be any of the 4 states of matter.
Glass being a liquid? I'd never heard of that before so I presumed it was BS straight away, since it's the sort of thing that would peak my interest.

FunkZ

Actually it's invisable.

Glass also happens to be a derived demand good. Now, that's what I learned in Economics

Tar.Aldarion

There is no clear definition of the distinction between solids and highly viscous liquids. You can argue either way.

MooseJam

what temperature does it freeze at so, also would be a good defense in court - but your honour you can't break a liquid

Stephen Fry says it's an amorphous solid.

Doesn't a viscous liquid have to behave differently at different pressures? Pushing lightly against my window doesnt seem to be doing much, hold on i'll push hard.....

cba looking it up now but IIRC the way old cathedral glass bulged at tbe bottom has more to do with the way flat glass was made than from flow. You glassblow a bottle, and then burst it with a tool and spin very fast to get a glass disk. BTW: The bullseyes are at the centre and were not used except by the very poor, so they are not traditional for pubs.

Sorry. I don't even understand the most basic scientific theories and regularly failed science at school, having to drop down to the ordinary level paper in Junior Cert... so I'm insecure on that front.

lol nerd? As someone who failed chem in my LC, I'll take that as a compliment I've just always been fascinated by chemical elements from a young age

Water is a simple concept to illustrate my point: put it some place cold and it turns to a solid, at very low temperatures it can be harder than steel.
Bring it to a point between 0 and 100 celcius at normal pressure and it's a liquid.
Bring it above 100 and it vapourises, turns to steam.
As capt said, place it in a vacuum and it will also vapourise.

The point being that almost anything can be said to be a liquid, gas or solid (not sure about plasma) depending on it's surroundings. Any metal when molten is a liquid, any gas when cooled sufficiently is a liquid.
These are pretty simple concepts...

Ice is made from Water. Water is a Liquid Ice is not. and there is noting amiss. Its just changing states of Matter.

remember the Liberty ships in WWII they had very brittle steel below 9C and many cracked in half in artic waters. Hardness at low temperatures is not always a good thing

and mercury is a great metal to make bells from

temp is a funny thing magnetic ones aren't above the curie tempertature and uranium/plutonium change volume because with termperature

kona

its a liquid
