Since it _is_ Friday and all...
volume be?
Where the heck do silent letters come from?
As I understand it, before the invention of the printing press, words
didn't have standard spellings. You just spell the word approximately
how it sounds. The first printers fixed the spelling of several words.
(E.g., "put" is spelt with a "U" because that's the letter that could be
printed most clearly. Nothing to do with phonetics.) This utterly fails
to explain why words like "knife" have a "K" in them. (!)
What the hell is the actual *point* of LinkedIn anyway?

3 l of water (pure) is a mass of (approximatively) 2.985 kg.
2.985 l.
The difference is therefore of 0.015 l, or 1.5 cl ( a glass of water is
about 15 cl usually (well anywhere from 10 to 30), so that's about a
tenth of one glass).
The variation of volume is about an half percent.

If you continue to cold it, it dilates again.

Uh, I beg to differ. Actually I distinctly remember watching a TV
and is only liquid because 1) it's salt water, but more importantly 2)
it's under a few thousand atmospheres of pressure.

Your random wonderings are out of sequence. The previous one was
#37648457, this one precedes it numerically but post-dates it. Are you a
time traveler? ;)

To network with professionals. But to be useful, you have to have
accurate information in your profile (IIRC, you don't list your actual
employer, for example). That makes it hard for people to find you.

I'm ok with 1 (H2O with NaCl is eutectic solution: solidus at -21°C,
liquidus above, at normal pressure, for 23% salt in mass, which is not
the case of the sea water (rather 3 to 4%)), but 2 seems bogus: when
pression increases, the states move from gas to liquid to solid (unless
you are on the diagram part where liquid is gone away... well there is
also a part of high pressure where liquid and gas are not separate...
for high temperatures).

I'm not 100% sure that holds true for substances where the solid has more
volume than the liquid, tho. I mean, sure, eventually you get into ice II
and ice III and such, but that's not what's going on here.

Actually, when external pressure increases, the melting point of water
goes down:

Here's one explanation. Not 100% sure it's correct:
