Primary Water & Water on Mars

There is a new form of water called 'Primary Water' that puts forward that water can be formed by chemical processes deep inside the earths core. This might explain the recent discoveries of water being found on Mars (yet there is no atmosphere to produce water). This would be an interesting addition to 'Source of Water' in the wiki article. See Primary Water for additional infomation. —Preceding unsigned comment added by Bacubanja (talk • contribs) 23:56, 12 July 2008 (UTC)[reply]

Water and life

I think an article about water and life would be a good offshoot from this article (redirects to include life and water and water in biology. It could discuss the properties of water and how they allow life to thrive, osmosis, and other areas such as life in water. Richard001 (talk) 05:36, 6 March 2008 (UTC)[reply]

Sound reasonable. Now we just need someone to write it... --Itub (talk) 17:43, 7 March 2008 (UTC)[reply]

"Water can be used to cook foods such as noodles."

Call me redundancy. --Leladax (talk) 02:26, 14 March 2008 (UTC)[reply]

change the first sentence

"essential to all known forms"

should be changed to

"essential for the survival of all known forms"

I

n the very first sentence. It is unclear in what way water is essential.

Good point! I will go and Change it now --Stealth (talk) 10:49, 14 March 2008 (UTC)[reply]

There is a mistake in "about 1,460 teratonnes (Tt) of water covers 71%....." Correct is 1,46 exatonnes —Preceding unsigned comment added by 88.217.39.242 (talk) 17:14, 17 March 2008 (UTC)[reply]

STATEMENT OF BOILING POINT

When presenting such data as a substances boiling point or melting point it should be made abundantly clear that the data is according to STP conditions is applicable. For example, water boils at 100C under 1atm of pressure or 14.7 psi. —Preceding unsigned comment added by Quidproquo2004 (talk • contribs) 02:54, 7 April 2008 (UTC)[reply]

"Water in the universe"

The figures given for Earth and Mercury seem to have become mixed up if they are not erroneous. A figure .002% is given for Venus but Earth as having a trace, I would say a trace is always less than a cited number. Giving the atmosphere of Mercury a definite water vapour content of 3.4% for a planet with an atmospheric pressure in the region of 10^-15 does not inspire confidence without a reference.Damorbel (talk) 10:21, 8 April 2008 (UTC)[reply]

Habitable Zone picture

The HZ paragraph states that earth would not have liquid water if it were much further away from the sun. However, according to the picture immediately adjacent, the HZ extends to about a third further away from earth's orbit, clearly more that "slightly further." 24.252.195.3 (talk) 02:44, 11 May 2008 (UTC)[reply]

Some rather useless info here

including, but not limited to, the fact that the freezing and boiling points of water are affected by addition of a solute. This is true for the vast majority of fluids. A statement about the value of water's constant for this property might be more useful, but in any case the food processing section seems to be too little about water - or food processing for that matter - to merit inclusion here. —Preceding unsigned comment added by 69.121.223.26 (talk) 04:04, 21 May 2008 (UTC)[reply]

Phases of Water

In the book "A Short History of Everything" by Bill Bryson, He mentioned that water has at least 9 phase. I do not know any besides the 3 common phases (liquid, solid and gas). May be supper cooled and under pressure it might be still liquid, I do not know, but think that it would in this article. mark45n Mark45n (talk) 15:34, 2 June 2008 (UTC)[reply]

physical properties of real water

The "Chemical and physical properties" section is far too limited, somewhat misguided. This article should be about all water, real-world water in all it's glory: tap water, rain water, lake water, sea water, etc. We want density etc data for real water, not just pure-theory water. All of the other WP water data articles are currently limited to only pure water. Where can one find data on the physical properties of real water? -69.87.199.87 (talk) 11:01, 6 June 2008 (UTC)[reply]

Why does ice expand?

"The maximum density of water is at 3.98 °C (39.16 °F)[5]. Water becomes even less dense upon freezing, expanding 9%. This causes an unusual phenomenon: ice floats upon water, and so water organisms can live inside a partly frozen pond because the water on the bottom has a temperature of around 4 °C (39 °F). " but it does not say why it expands while usually cold things contract, I have always been interested in this.71.112.193.110 (talk) 01:15, 15 July 2008 (UTC)[reply]

POV opinion

"Moon - small amounts of water have been found (in 2008) in the inside of volcanic pearls brought from Moon to Earth by the Apollo 15 crew in 1971" there is no actual evidence that mankind has ever been to the moon, it is widely debated which renders this as a POV as it cannot be proven, only argued (like a creator or evolution) it is only a theory. It should at least read "Moon - small amounts of water have been found (in 2008) in the inside of volcanic pearls claimed to have been brought from the Moon to Earth by the Apollo 15 crew in 1971" in order to avoid "theory as fact" claims.71.112.193.110 (talk) 01:15, 15 July 2008 (UTC)[reply]

Erm, Why?

Why is it protected? I saw some bad grammar, and I wanted to change it, I looked at where the edit button is usually, and it showed that protected icon? ~~Sealim~~ (talk) 21:31, 22 July 2008 (UTC)[reply]

food processing -water hardness

I propose to link to the page on hard water. Therefore the text

"Water hardness is also a critical factor in food processing. ... and hard if it contains 11 to 20 grains. ^[vague] ^[1]"

should be changed into:

"Hardness of water is also a critical factor in food processing. It can affect the quality of a product as well as play a role in sanitation. Hardness of water is determined by the concentration of calcium and magnesium."

Original Research

Is it because we can't find any o.r. ? Because no where in this article does it say that water is wet. And we can't just say that cause as you know on wikipedia If A = B and B = C, then A only equals C if The New York Post or MONGO says it is true. --72.221.91.140 (talk) 03:22, 29 August 2008 (UTC) (troll form ED, A=B thing and concept is from the article Original Research on Encyclopedia Dramatica)[reply]
