Properties

Egregiously bad. The density of ice is NOT a constant. This is grade school physical science and yet this article claims the density has a specific value! Sure, at 0 C, 1 atm pressure, 1 Gravity acceleration, pure water with a given isotopic constitution will, at equilibrium, have a specific value. But the simple claim that "ice has a density of X" is a great example of incompetent editing.174.131.48.89 (talk) 19:46, 29 July 2022 (UTC)

Water cycle

I am currently working on the article water cycle and came here to see if there is useful content here that I could repeat at the other article. The section on water cycle is not bad, however hardly any references are used. Should this be corrected or is it deemed acceptable since the statements are so broad and well known? Also I am thinking of using the excerpt tool to add an excerpt from water cycle. What do you think about this suggestion? EMsmile (talk) 21:28, 28 September 2022 (UTC)

Modern or Ancient Greek

In the etymology section it is stated that a cognate of 'water' is Greek ύδωρ (ýdor). I think it might be better to be a bit more specific and say 'ύδωρ' is Modern Greek, as it might easily be mistaken by the similar Ancient Greek word ὕδωρ (hýdōr or húdōr, with spiritus fortis and relevant long 'o'). -37.11.122.76 (talk) 12:17, 29 October 2022 (UTC)

We just have a paper published in Science, we would like to make such changes: Water (chemical formula H2O) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent[1]). It is vital for all known forms of life, despite providing neither food, energy, nor organic micronutrients. Humans comprise 40 to 70% water and turnover about 10% of this every day. . Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°.[2] "Water" is also the name of the liquid state of H2O at standard temperature and pressure. 199.48.182.28 (talk) 02:44, 1 December 2022 (UTC)

• I don't know what changes are being proposed here--unless it's just the addition of a published paper, which isn't necessary for this lead. Drmies (talk) 02:47, 1 December 2022 (UTC)

Change the second line of the article, "It is vital for all known forms of life, despite providing neither food, energy, nor organic micronutrients," to "It is vital for all known forms of life, despite not providing food, energy, or organic micronutrients." Many style guides, such as The Chicago Manual of Style (entry 5.234) and Garner's Modern English Usage, agree that "neither ... nor" constructions are best limited to exactly two items in a list.

Change paragraph: “ The surface temperature of Earth has been relatively constant through geologic time despite varying levels of incoming solar radiation (insolation), indicating that a dynamic process governs Earth's temperature via a combination of greenhouse gases and surface or atmospheric albedo. This proposal is known as the Gaia hypothesis. ”

To

NEW PARAGRAPH: “ The Gaia hypothesis suggests that the biosphere actively engages in self-regulation, maintaining the Earth's environmental conditions suitable for life. One proposed mechanism for this regulation involves feedback loops related to climate, such as the one stemming from marine algae. When temperatures rise, these algae produce more of a volatile cloud-seeding chemical, dimethyl sulphide, which stimulates cloud formation, subsequently reflecting radiation back into space and cooling the planet. ” SOURCE: Gillon, J.

I am inclined to reject this edit request. I'm not sure that dimethyl sulfide is the best example of how temperature is regulated in the Gaia hypothesis. And, regardless, it is unclear why this detail should be in an article about water. Walt Yoder (talk) 23:22, 15 June 2023 (UTC)

Electrical Conductivity and Electrolysis

“The decomposition requires more energy input than the heat released by the inverse process (285.8 kJ/mol, or 15.9 MJ/kg).” This is in clear violation of conservation of energy. Perhaps what they intended to say was that electrolytic decomposition is not 100% efficient? Mindyobusiness12 (talk) 13:46, 29 December 2022 (UTC)

Molecular polarity

• What I think should be changed (format using {{textdiff}}): Under the molecular polarity paragraph it states "oxygen atom retains a negative charge while the hydrogen atoms are positively charged." this is technically wrong it should be a partial negative charge and hydrogen partial positive charge
• Why it should be changed: its wrong
• References supporting the possible change (format using the "cite" button):
