Rfv-sense "Any volatile chemical, such as water, ammonia, or carbon dioxide, not necessarily in solid form", as distinct from the preceding sense, which is such a chemical when solid / frozen. Wikipedia says this sense is why "Jupiter and Saturn are gas giants, and Uranus and Neptune are ice giants, even though the vast majority of the "gas" and "ice" in their interiors is a hot, highly dense fluid", but when I search google books:"ice giant" "liquid" trying to find cites, the cites generally say that "ice giants" are so called because they have significant ice (frozen, solid matter) as a distinctive feature, irrespective of whether they have other, non-distinctive features like fluid interiors that planets commonly have. And I'm not seeing any relevant uses at e.g. google books:"liquid ice" or "liquid ammonia ice". - -sche (discuss) 06:17, 20 October 2022 (UTC)
- I think the definition might need to be tightened up by someone familiar with the topic but it seems to be a real thing: see the reference to a "liquid mantle composed of ice materials" here, the diagram caption here that jokes "Only astronomers could call a 2000 degree fluid “ice”", and the explanation of the "ice" in ice giants as a "hot, slushy mixture that would be more aptly described as a water-ammonia ocean" here. —Al-Muqanna المقنع (talk) 10:49, 20 October 2022 (UTC)
- Interesting! This may be real, then. I'll see if I can go through those citations later. - -sche (discuss) 10:56, 30 December 2022 (UTC)
- Withdrawn, with two clear citations thanks to Al-Muqanna. It's hard to find a third unambiguous citation because things like "the fluids of the hot, ice-rich region of Uranus and Neptune" or "the core is surrounded by a hot ice-rich liquid envelope that merges imperceptibly into the hydrogen-rich atmosphere" (Citations:ice) could still be using the usual (frozen) definition of ice and discussing fluid that has ice (frozen chunks) in it — it's hard to find examples which are unambiguously using ice to refer to something which isn't frozen (outside of the context of referring to something which was previously frozen, e.g. "melted ice", a situation the usual water-ice sense can also be put into) — but I suspect one exists. - -sche (discuss) 17:57, 31 December 2022 (UTC)
Cited, added a quote talking about "solid or liquid ice" which seems clear enough. Ioaxxere (talk) 23:20, 10 February 2023 (UTC)
