@DnlStnYtbr The technical definition of viscosity: a liquid's resistance to flow. For example, honey does have a higher viscosity than water because it has a higher capacity to resist flow. Therefore, it flows less quickly and changes direction less readily.
This is probably a redneck question but I need to ask. What would happen if this touched you? Since it is a very low Kelvin number I would imagine either it would literally burn right through you or it would completely freeze everything from the contact point through the rest of its position on your body, say the arm. But what would really happen?
@gaarafan93 Besides killing the tissue it touches, having a temperature of 2 Kelvin, the fluid will most likely just slip off your hand onto the floor, or maybe even climb on the surface of your hand. As it has been observed with liquid helium at 2 K, it can climb out of a container. But in my opinion it will slip off causing burns to your skin.
As far as I see it, the movie could be a superfluid, which is expected to pinch like an inviscid fluid, because it has zero viscosity. It has been studied in the following paper: pre.aps.org/abstract/PRE/v75/i3/e036311. @FishBow Surface tension is not related to viscosity, they are two different quantities not originating from the same cause. Because superfluids have an interface with their surroundings they do have an interfacial tension, as low as it can be....
Surface tension is a result of viscosity. A superfluid would have zero surface tension and thus would flow upwards and spill out of an upright container. This video is wrong. A superfluid would not drip, it would flow out like a smooth waterfall through even the smallest cracks or out that nozzle. This clearly is just water.
surface tension is what holds the drop together, not viscosity, if a fluid has no viscostiy that means it can escape through very small pores in glass, meaning you cant contain it that easly, also if you jump into a pool filled with a super fluid, it would be the same as jumping into a pool or air, you wouldnt slow down, you couldnt even swim out. it would be like trying to swim in air put your surrounded by a fluid. wierd isnt it?
Viscosity is the internal resistance (some call it "internal friction") of a fluid against flow. It has nothing to do with holding a fluid together or dripping.
A superfluid has zero viscosity, meaning that it does not resist flowing in itself. If anything, I'd say that actually allows it to form drops. This is proven by the videos of superfluid helium "creeping" up the walls of a bowl against gravity and forming drops below to equalize the helium level.
How overwhelmingly uninteresting. It drips no differently then any other typical fluid....like water, urine, mucus, or post-Mexican-cuisine diarrhea. I would have thought it would have some unusual type of drip.
Liquid helium is said to no viscosity at all and is capable of defying gravity. What baffles me is that it leaks through its container. I quess helium should be called the weird-fluid.
omg u say it lookl like this fluid has viscosity? lol viscosity is the abillity for a substance to flow....... root word of which is fluid... thats what a fluid is... a substance with viscosity.... lol sry i thought that was funny...... hmmmm looks like this fluid is fluid.... interesting lmao
Actually viscosity is how much a liquid resists flowing, essentially how much the liquid clings to itself (i.e. honey is more viscous than water). The liquid in the video is clinging to itself and is therefore not a superfluid because it has viscosity.
I'm not sure what this was supposed to show relative to superfluidity. Can someone explain what this is supposed to show? It looks like a normal pinchoff, or was it to show that superfluids pinchoff the same as normal fluids?
it's called high speed because of the extremely high framerate of the camera. it takes anywhere from 3000 to 30000+ frames per second, catching everything that is missed by the naked eye. whenever you see high speed footage it is always slowed down (like on this video) so you can see exactly what's going on.
As much as I hate to spoil the fun for you techno-geeks, this is not, i repeat _not_ a superfluid. The ability to form drops is closely related to viscocity and surface tension, two things a superfluid lack.
No, this might just as well be a drop of water from from you own toilet sink fauset in super slow motion. Still pretty cool :)
@nesnahsleort So why does the superfluent helium form drops as it drains the elevated cup, as show in several videos? Superfluid helium indeed has surface tension, but no viscosity.
@nesnahsleort no this is a superfluid when they say that it has no viscosity they mean that if you put it into a container persay a beaker as soon as the gas gets to the liquid point it will flow out of the beaker, also another property of a superfluid is if you put it into small semi circle container it will flow towards the opening of the semi circle as if gravity does not apply to it
@nesnahsleort As others have pointed out, a superfluid has zero viscosity, not zero surface tension. Drop formation requires surface tension, not viscosity.
@nesnahsleort : Lol ... you're still getting flack from a 2 year old comment. I'm gonna do it anyway :P
If there's no surface tension then it would be gaseous. Surface tension is an inherent property of any liquid. As said before, surface tension and viscocity are two seperate properties. The only way to remove surface tension is to turn it into something without surface : gas.
Actually, gasses have surface tension too. It's just really small. If you do an in depth analysis of the angle of beading liquids on a surface, surface tension is an interface force between areas - solid-gas, solid-liquid and liquid-gas all have an impact on the resulting bead of fluid. The net result of all this is the angle at which the bead contacts with the solid, which is used to describe the hydrophobicity of the solid. Very useful in mineral processing, though the force analysis isn't
anshulkamboj shut up! I just didn't know what the word meant, but now I know. There wasn't really a point in thumbing down my comment once. I didn't have to reply to ytscreenname.and you need to mind your own!
Superfluids have low viscosity (i mean really low, e.g they can go through material) which means, that there's no way that this drop would have such a length.
I completely agree. Also, i thought it was a pure boson in that in order to get any of it to move you need to get all of it to move. So why would there be a drip?
Just watch the movie about liquid He here on youtube, they put some of it ina glass vessel and it comes up and down the walls and the drips from the bottom.
I have watched that video several times. And as mentioned by that demonstration liquid helium has LOW Van Der Waals forces between the atoms/molecules. Just to inform that VDW forces lowers as me transfer from liquid to gas. In that drip you mention, the helium makes VDW bond ALSO with the glass. In this video it only makes bonds with other SIMILAR molecules.
lol! hello there, LordOfTheGnus~I was actually thinking about the double torus & coralis effect of the earth, the theory of it anyway. such is the danger of me posting comments for videos on anything even resembling physics (unfortunately they only gave us the science they thought we needed for nursing school. definitely a layperson here). (o; but having fun learning about what interests me. sent you a video that addresses these theories. the specific information starts 4 minutes in.
actually, if you spill supercold liquid gas on your body, it would instantly evaporate and form a layer of gas between your skin and the liquid. but if you jump into a liquid gas you WILL freeze.
a liquid substance that is usually a gas. example: liquid nitrogen. 308813062 was talking about these kinds of substances that become liquid at super low temperatures.
I'd like to thank the scientific community for keeping us all ignorant as to what this really means. typical parlance...I'm not at all surprised but geez...there are geniuses out here who want to be a part!

superfluid is a state in which is below solid, A substance that reaches superfluid is REALLY close to absolute zero, which means there is absolutly no heat in it at all, in a superfluid state the atoms start to act like energy instead of like particles, and atoms cannot distenguish themselves between eachother. therefor the properties get mixed up and they act extremely different.
Sorry if theres any mistakes, this is coming from a 13 year old boy so dont get mad.
LOL that was funny as hell when it came off i was like started laughing and stuff i was like that was awesome it was like a yoyo it went back up but then the top broke so it went back down
I don't get it. Was that like maple syrup or something. I have no background in physics, but when I was a child it amused my curious mind. This drop proves time travel possible if my grandma's uncle had gone to community college and taken basic physics and was able to get me an early start when I was a wee mang. But alas, I clean out loos at a nursing home. Damn you cruel universe!
if there is no friction wouldnt that make it possible to create perpetual motion, if the supersolid was made into an engine or generator of some sort?
No, because the generator or motor would lose energy through whatever it was attached to- you'd have to end up with more energy than you started with, which violates the law of conservation of energy.
This comment has received too many negative votesshow
funny thing is i dont want perpetual motion just very cheap motion,just remember when excuses for perpetual motion are given to cheap energy,i beleve e=mc2 isnt just with attomic energy and distroying matter but to tease it.but im mad and cant spell :)

Ideally, shouldnt there be no cohesion whatsoever?
sandcrab132 3 years ago
Yes, if that is helium-4 beyond it's lambda-point, there should be no viscocity at all. So the "dorp" would simply fall down as a stream.

So, technically this wouldn't be a superfluid then, correct?
sandcrab132 3 years ago
correct, I think this is just a slow-mo water drip.

I wouldn't be able to tell the difference between this drop and a water drop.

LOL that was funny as hell when it came off i was like started laughing and stuff i was like that was awesome it was like a yoyo it went back up but then the top broke so it went back down

The drop isn't speed up. It's high speed video. I.E. this whole process occurs in milliseconds. I should know I'm in this lab. :P

I don't get it. Was that like maple syrup or something. I have no background in physics, but when I was a child it amused my curious mind. This drop proves time travel possible if my grandma's uncle had gone to community college and taken basic physics and was able to get me an early start when I was a wee mang. But alas, I clean out loos at a nursing home. Damn you cruel universe!

the fact that your handle is krebscycler proves that you probably do not clean out loos.

lol I was cheering on the little drop at the end to catch up with the big one.. wonder if the lil guy made it :P

how long would this drop take if it was not sped up?

at the point of transition between solid and liquid?
which gives it the elasticity that we can see after the main drop has pinched off?
TimJamMer 3 years ago
Is that video so fast we perceive it as slow? Someone tell me please, I'm confused.
DefinedStar 3 years ago
No, in real life it fell much more slower. The drop is very very cold, 1.34ºK (-271 celsius), so it's sped up so we can actually see it move.
Azarathos 3 years ago
oh ok, so if it was hot, then the video could be slower to show the drop falling??
sstacman 3 years ago
it wasnt hot, it was 1.34 kelvin
thats equal to about -272.66 celsius!

wouldn't it be frozen solid???

Degrees ABOVE absolute zero
blaa94 3 years ago
no, because helium doesn't form a solid at temperatures above ~200 mK, and then it forms a supersolid.
vehicar 3 years ago
kool haha never knew that.... whats a supersolid?
corezero09 3 years ago
a supersolid is a solid that has some superfluid properties- namely, no friction and attraction to heat sources.
vehicar 3 years ago
if there is no friction wouldnt that make it possible to create perpetual motion, if the supersolid was made into an engine or generator of some sort?
laxelite 3 years ago
No, because the generator or motor would lose energy through whatever it was attached to- you'd have to end up with more energy than you started with, which violates the law of conservation of energy.

funny thing is i dont want perpetual motion just very cheap motion,just remember when excuses for perpetual motion are given to cheap energy,i beleve e=mc2 isnt just with attomic energy and distroying matter but to tease it.but im mad and cant spell :)
kevinstuartfr0st 3 years ago
You would have to have it be repelled from the whatever was holding it. That could also act as the driving force.
