Online publication of 3 general articles on the properties of water:
1) General and curiosities: https://www.econologie.com/les-propriete ... s-545.html
2) Physical and chemical properties: https://www.econologie.com/les-propriete ... -3144.html
3) Isotopes and molecular structure: https://www.econologie.com/les-propriete ... -3145.html
And yes ... water is really a strange element and we are far from knowing everything (this is rarely said in class) ...
It is surely not for nothing that it is at the origin of life ...

good evening Christophe

For my part, I never checked
By the way, I put "bar" in the singular, is it an invariable word like "euro" ?, and never takes s. Is there a French teacher who can confirm?
It's true that when you have more than one bar (or more than one euro), you always want to put an "s"

2) The ice water passage is done with expansion: if the water occupies a constrained volume, the container undergoes colossal pressure (more than 200 bars).

Hello
Very interesting we learn it every day.
If we apply this principle to the bubbler, by dint of adding water to the bubbler, there are only heavy isotopes in the bottom?
it might be a good idea to purge the bubblers from time to time and leave with fresh water. Wearing once I forgot to add more and the bubbler has completely dried up.
the water which remains in the bottom of the bubbler has a brownish color, however it is entirely made of tinned red copper.
I will end up believing that water with impurities and higher al, distilled water, I always start my reactor with water pumped from a well which contains more sediment, then rain water, and now water from tap with vinegar.

Ocean water evaporates with isotopic fractionation: the light isotope of oxygen evaporates in preference to the heavy isotope. Oceans are richer in heavy isotopes than cloud and precipitation water

Hello,
It seems to me that, like most of the units, bar is variable.
Euro would be an exception ??

This is not because we always said that it is impossible that we should not try

1) I don't understand your hint at all) the cow ...
2) for the 200 bar small typing error, I forgot a zero which I will add immediately
For André: I do not think that the low proportions of heavier isotopes in water do anything in a bubbler compared to other factors (dust, rust ...).

You quibble but it's just ... as the sea salt water is denser there is more than 8% emerged ... but as the salinity of the sea water varies enormously from region to region other I prefer to refrain from putting forward precise figures ... moreover we are still talking about 5% for icebergs ...
