Is a single molecule of water wet?

[–] [email protected] 43 points 10 months ago (2 children)

I asked my chem professor this question last semester. He said that single molecules are considered gases.

Which is an interesting thing, actually! States of matter are not related to the molecules themselves, but how they interact with themselves. It's an emergent property! Not something intrinsic!

Yup. The way he explained it was that it is technically a free flowing substance that is "expanding" to "fill" the container it is in. The density would be impossibly low, but the entire container would be said to be filled with the molecule

Someone correct me if im wrong, but i think humid air actully has liquid water in it

Is it not gas?

[–] [email protected] 1 points 10 months ago

that's fog

as long as you can still see through it, the water is gaseous

[–] [email protected] 5 points 10 months ago

I think in the sense that it's not surrounded by water it's dry, but in the sense that it has water-like properties it is wet.

Idk if this is good enough, but I'm using this for my PhD thesis. (Just this image, no long winded paper or anything).

Dry water is a real thing, it's water molecules not allowed to combine by silica Google dry water it's super interesting
