Talk:Superheated water

Anomalous Behavior Comment

The example of anomalous behavior is quoted from an email. So, it should indicate this in its discussion, with a citation made pointing one of the rather numerous hoax discussion sites that talks about the email. I think it would probably be appropriate to scrap it in favor of a mention of Mythbusters episode 0104 instead, though. —Preceding unsigned comment added by 128.113.139.187 (talk) 20:20, 8 May 2008 (UTC)

The behaviour cited is specifically watrer at atmospheric pressure heated above its boiling point, and therefore metastable. This article refers to stable water under pressure. There is an article Superheating which covers the behaviour described. This is mentioned in the lead section, but perhaps the destinction needs to be made clearer.Stainless316 (talk) 14:25, 13 May 2008 (UTC)

Change of properties with temperature

I was slightly confused when I read this sentence:

This means that the concentration of hydronium ion (H3O+) is higher, and hence the pH is lower (although the level of hydroxide (OH-) is increased by the same amount so the water is still neutral).

Is the pH lower? or does it stay the same? If it starts out neutral and the pH is lowered, it can't still be neutral, right? Braincricket (talk) 09:23, 21 November 2011 (UTC)

Sounds odd, doesn't it, but it is correct. pH7 is neutral at room temperature, but at higher temperatures neutral pH is less than 7. This is because the definition of neutral is equal concentration of H+ and OH-, whereas pH is defined by concentration of H+ only. At room temp, if the pH is less than 7, it is impossible to have equal concentration of H+ and OH-Stainless316 (talk) 12:12, 30 November 2011 (UTC)

Superheating produces super hot but not superheated water???

I was trying to find how hot water heated without nucleation can get, but found that according to the wiki page on superheated water, it does not include water that is made super hot from superheating water?!?!

Can such water not be considered a class of superheated water?

Also between this and the page dedicated to microwave superheating of water I still have no idea how hot the water might be. — Preceding unsigned comment added by 121.99.188.97 (talk) 06:44, 10 February 2014 (UTC)

For example, instead of 190 nm, use 190 nm, which when you are editing the page, should look like: 190 nm.[?] Per Wikipedia:Manual of Style (headings), headings generally should not repeat the title of the article.

(You may wish to try Tony1's redundancy exercises.) Vague terms of size often are unnecessary and redundant - “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, and “all”. For example, “All pigs are pink, so we thought of a number of ways to turn them green.” As done in WP:FOOTNOTE, footnotes usually are located right after a punctuation mark (as recommended by the CMS, but not mandatory), such that there is no space in between. For example, the sun is larger than the moon [2]. is usually written as the sun is larger than the moon.[2][?] Please ensure that the article has gone through a thorough copyediting so that it exemplifies some of Wikipedia's best work.
