Good article Water was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

To-do list for Water: edit · history · watch · refresh
  • Article's purpose: Water's importance for life and humanity.
    • rewrite with purpose in mind (what is wrong with it now? has this been discussed?)
      • Discuss the dangers of water.
      • Expand appropriate short statements into full paragraph.
    • re-organization toward this purpose
    • missing topics within scope
      • Add a section on water-based power (hydroelectric, wave, tidal etc).
      • Water on other planets
    • consider deletions with this purpose in mind
    • spin-off topics tangential to scope
    • change types of water to forms of water.
      • please include the role of comets and meteors in bringing water to earth

[edit] 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)

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

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

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

[edit] change the first sentence

"essential to all known forms"

should be changed to

"essential for the survival of all known forms"

in 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)

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)

[edit] 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)

[edit] "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)

[edit] 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)

[edit] 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)

[edit] 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)

[edit] 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)
