Can we make liquids like that? Sounds useful in some situations.
You can not “make” a given liquid like that but there are some liquids with low surface tension. From the back of my head I remember the Avogadro experiment, but to lazy to look it up. What I recall is that he “counted” the amount of particles in a drop of oil because it forms a mini layer of lying on top of water. You might notice when you drop a bit of oil in water, that it always creates a giant puddle.
Back to the original post: that thin layer of water would just evaporated instantly
we also wouldn’t have icicles :(
You can add a wetting agent to water to decrease the surface tension
wetter water
Add more water
Would that mean that if you jumped into the Atlantic you’d just fall to the bottom? Or would that be due to buoyancy or something
Buoyancy (different densities).
I’m really dense though
See you at the bottom
We would not have life! Water is a polar molecule that is very different from most other liquids. Its the specific surface tension properties that help to create life. The reason why we search for planets with water. We’ve never worked out a way for any life to exists without the amazing H2O.
Now imagine what wonders we could have if there were a few other quicky molecules.
What if it just applied to chlorinated tap water then
look…I’m just glad roaches don’t have sharp teeth and spiders can’t fly.
let’s stop while we’re ahead
When some spiders are born, sometimes hundreds at a time, they cast little parachute webs and ride the wind to wherever they might go.
Palmetto bugs are like mean flying roaches that bite.
You’ll never escape the horrors of the beauty in nature.
Let’s stop
while we’re ahead
The water would react similarly to alcohol. Yes, the puddle would be bigger but it would evaporate faster.
Then your cells would die and plants wouldn’t exist
Well if water didn’t have its unique properties of cohesion and adhesion we likely wouldn’t be here anyways.
Now think about what would happen if ice didn’t float.
I’m not a geologist, but I’m imagine that the deep ocean would be a colossal underwater glacier, with intermixed sedimentary layers. Kind of like what we have with methane hydrate deposits, only much, much deeper. The super-deep ocean simply wouldn’t exist, and we might not even know about the Mariana Trench, or a lot of other sea floor features. Also, it’s possible a different proportion of the world’s water would be frozen in this way.
With ice as a part of the sea floor, it would also interact with subduction zones at continental edges. That might push a LOT more superheated water into volcanoes, faults, and everywhere else water could go. That would probably make for a lot more geysers in such areas, and volcanic eruptions would be far more energetic.
The trajectory of human history and technology would also be changed. There might have been fewer ice bridges between continents during the last ice age. Ice-skating wouldn’t become as common a thing until we get refrigeration. Harvesting ice in the winter would require bodies of water to freeze solid first, making it impractical except in shallow areas.
I’m also going to wager that glaciers would behave differently too. I don’t know enough about their dynamics, but I wonder if having meltwater on the bottom helps lubricate their movements somewhat. Kind of like a lava flow, only slower. Inverting that relationship might make glaciers far less mobile.
Yeah, not good. It’s kind of a weird quirk of nature that water is pretty unique in that it gets less dense when it’s a solid as well.
Hmm, might small bodies of water, say pusdle to pond size, still freeze from the top down because of exposure to colder air and above freezing earth? If the top freezes over all at once it might stay on top unless something breaks it and allows water to flow from under to over
at least it wouldn’t wet your socks. i think capillary action relies on surface tension
It relies on differences in surface tension. If a liquid has a lower surface tension (energy) towards one surface than another, you get the typical capillary effect. In the case of water, the water-air energy is lower than the water-<whatever your capillary is made of> energy, so you get a capillary effect.
If water had exactly zero surface tension against every interface,
- it would not exhibit any capillary action
- life on earth would cease to exist quite quickly
- your socks would remain dry
life on earth would cease to exist quite quickly
your socks would remain dry
For a liquid to be a liquid, rather than a gas, it needs to be held together by intermolecular forces. Which means it will have some amount of surface tension. I therefore dismiss this hypothetical as physically unrealistic! :P
supercritical helium does some really weird shit, I’d call this one plausible.
Supercritical fluids are more like a gas than a liquid. Their lack of surface tension means they’ll diffuse throughout whatever container you put them in, so they can’t really be “poured” like a liquid can. They’re actually a pretty good example of why liquids need surface tension to be liquid.
I think they meant to say superfluid helium.
that’s a pretty good point, it’s literally trapped between being a liquid and a gas. If this was BattleBots, they’d let it compete once and then ban it.
“Trapped between liquid and gas” is kind of the opposite of what a supercritical fluid is. It’s more that gas and liquid states are “trapped” in a region of phase space, while supercritical fluids exist in the place where the demarcation between the two no longer exists (which is usually a far larger region than where it does).
Superfluid. It can be supercritical, but superfluid is the special thing for helium.
You do some pretty weird shit.
Oh, snaaaaaap.
supercritical
does some really weird shit
I’m no geologist, but I could have guessed that without any further specifics 😉
Unless its a hydrocarbon product, which can (and does) spread over surfaces it can’t mix with/soak into in single molecules thick sheets.
Aha! But languical constructs allow and do allow hyperboles! So it could be argued that the colleague asked for the minimum allowed by our bindings law!
I request a motion to dismiss your dismissal :>
wouldn’t this evaporate extremely quick though?
Yeah, I’ll often spread spilled water across the table just so that it evaporates within a couple minutes.
Must be nice living somewhere dry. I’d just end up with a moldy table a day later.
This reminds me of the person that suggested in a response to a request for ADHD “life-hacks” where they would wet one of their socks before starting a specific high-importance task and could not take it off until the specified task was completed.
I see, quite similar to the ol’ light-your-hair-on-fire-to-motivate-yourself-to-shower trick. Clever!
That is a weapons-grade life hack right there.
That’s how gasoline spills (on water) work. They cover the water about one molecule thick.
So you’re saying my floor needs to be water?
