So if you combine all the gases in air in liquid form could you drink it to get the air you need in your system instead of breathing? If you had enough of course.
@PyroJuggalo2021 Ignoring the freezing to death issue, it still wouldn't work. Your stomach doesn't do the same job as your lungs. The 'air' would be ending up in the wrong place if you drank it.
@TheFindip Nitrogen makes up 78% of the air, so you're looking at normal nitrogen right now. Liquid nitrogen is so cold because it has to be so cold to be a liquid.
Have you guys seen the orange LED in liquid nitrogen video? Causes it to change colors to yellow, and towards green. You guys should try doing that and explaining it! Very pretty as well.
What if you mix liquid oxygen and liquid nitrogen? Also after that what if you try to set it on fire or pour it between the magnets? What would happen???
@SticksNBones24 Nothing chemically happens when you mix the two. You just get something that's similar to liquefied air, depending on the ratio of nitrogen to oxygen. It won't burn without a great deal of effort and pouring it through the magnet would tend to separate the liquid oxygen from the liquid nitrogen.
Did you see that super magnet before? It made the lab folks so giddy they put pieces of pizza in it just to watch it float from the magnetism. You could easily observe liquid nitrogen floating there.
@JeffersonLab It's this super magnet of course that's really old news; but the force is so strong you could make things considered non magnetic to float in the chamber pizza, live frogs, gold, water, so on and so forth.
@JeffersonLab, On Titan methane is a liquid and it does not burn because there is no oxygen. If you allowed oxygen in to titans atmosphere and lit a match want would happen?
@JeffersonLab@ironicstatement Jefferson lab was partially right; yes it wont burn frozen but it's the vapor's that are flammable not the liquid gasoline it's self.
@darkheat246 Sorry, but how am I partly right? How is "Solids don't actually burn. They first have to be converted to a gas." different than what you are saying?
I'm a bit of a science nerd, and have come across paramagnetism before (not diamagnetism, however- thanks for that one). However, I have never seen how it works. Can you explain why either happen?
@Iamnemo1994 Not simply and not within the 500 character limit. The hyperphysics site is a good starting point. Doing a search for 'hyperphysics paramagnetism' should get you there.
Awesome! .. It seems that the cloud of oxygen tends to get closer to the magnets as the temperature rises, but at the end it disappears completely.. so, does the paramagnetic effect becomes weaker as the temperature rises? Or maybe the oxygen is still around there but we cannot see it?..
@soulwarriorwithn Among other things. Take a look around the room. Things that are solid have frozen, things that are liquid have melted and things that are gas have boiled. Want a gas to become a liquid or a solid? You have to get it cold. Want a solid to become a liquid or a gas? You have to get it hot.
If I were to put liquid oxygen into a breathing apparatus and *drowned* myself with it, Would I still be able to breath? - Same thing comes to mind with the fluid in the womb of a pregnant women, which I don't remember where but I read that it could let you breath *under-water* if you first drowned yourself with the liquid, which is how baby's don't die when they are *baking*.
Something about being rich with oxygen or something.
@2Pluz2 You'd freeze to death before drowning becomes an issue. Also, while a fetus 'breathes' amniotic fluid, it doesn't get oxygen from it. The fetus gets oxygen from its mother via the umbilical cord.
@JeffersonLab Ok so if theoretically we could get Liquid Oxygen to not need to be frozen to be liquidized, if we have liquid oxygen in our lungs we could breath without dying from having water in our lungs? - Kind of confusing myself but I'm just incredibly curious of ways to let us breath without actually breathing...
@2Pluz2 It would depend on how well carbon dioxide dissolves in liquid oxygen. I also think that there are issues with breathing pure oxygen. However, given the right liquid, people can breathe liquid rather than air. Do a search for 'fluorocarbon'.
@hirokisa234 For a start you would have a VERY hard time drinking it. You neck muscles would be frozen almost instantly. Once the liquid reached your stomach it would freeze it and then expand back into its gasious state making you partialy frozen, dead, and bloated.
Pretty interesting. I've always wanted to try different things with LOX. Too scared to, well besides throwing nearby by bugs in the pan. :) Subscribing!
@aboriani It does happen. The molecular structure of gaseous oxygen is the same as liquid oxygen. You don't get oxygen gas building up at the poles of strong magnets because the speed of gas molecules is so high (rms for room temperature O2 is about 480 m/s).
@JeffersonLab well, then living near strong magnetic fields DO affect something in your body... or even the magnetic forces of planets or even stars... that would somewhat explain all that astrology talk...
@aboriani Of course, the magnetic fields you are typically exposed to aren't anywhere nearly as strong as the field between the poles of our magnet. We're talking several orders of magnitude here. The magnetic fields from other stars or planets have absolutely no measurable effect on you.
@JeffersonLab yes, but even being almost no measurable, they still there... the sea tides are there to prove it, and they are caused (in part) by a very small body, the moon. Of course, im not talking about short terms effects, like the horoscope, or stuff like that... anyway, im just speculating here hehe.
@aboriani The tide(s) is caused by gravity, not magnetism. And a total syzygy of the planets in our solar system (Which cannot happen) would have less effect than the magnet from your harddrive from across the room. the effect weakens exponentially with distance.
@aboriani Interesting question. It should, because the chemical composition of the oxygen is the same. However, It might not because the gaseous molecules have more energy than their liquid counterparts. In any case, we wouldn't be able to see it.
nice and thank you. nv studied magnetism growing up so i was kinda taken aback by the concepts of dia- and paramagnetism. The video helped me understand their effects, but would a scientific explanation of the phenomena that dives into the interaction betw the B-field and electrons be too hard to understand?
@kimdachi For our intended audience, yes. And, it isn't something that can be explained properly in a sentence or two. For those who are truly interested, it isn't hard to do further research now that they know the terms diamagnetic and paramagnetic.
@TheGingerGerman It's mainly the forces between the particles of a liquid that determines the liquid's boiling point at a given pressure. The weaker the forces between particles, the lower the boiling point will be.
@TheGingerGerman 0 degrees celsius is the freezing point of water at normal atmospheric pressure, the boiling points and freezing points of oxygen and nitrogen are much lower at the same pressure.
@TheGingerGerman Yes, nitrogen and oxygen are elements. But, you have never encountered atomic nitrogen or atomic oxygen. When you encounter nitrogen or oxygen, say, in the air, it's in the form of a molecule. Specifically, they are called diatomic molecules, molecules made from two atoms of the same element. That's why nitrogen is written as N2 and oxygen as O2. Calling them molecules is correct.
@JeffersonLab Really though in your video should have included that you had oxygen from the air. Pure oxygen (0) that is strictly made up of 1 type of atom with 8 protons and 8 electrons. It is a Molecule when greenhouse gasses (C2) covalently bond with oxygen making it a molecule. Therefore since so many humans today are polluting the air yes it would be considered a molecule or a compound. Diatomic elements which would include all of them except the noble gases are also considered molecules.
@TheGingerGerman No clarification is necessary as 'oxygen' is universally understood to mean O2. The source of the oxygen is also unimportant. Let's say that we obtained our oxygen through the electrolysis of water rather than condensing it from the air. The reaction for that is:
2H2O --> 2H2 + O2
and not
H2O --> H2 + O
Oxygen and hydrogen are both diatomic molecules. When someone says 'oxygen', they mean 'O2'. When they say 'hydrogen', they mean 'H2'.
I was thinking of writing a grant proposal to get a large magnet to do this demonstration for my students for when we study molecular orbital theory. Could you tell me the name of the company you ordered the magnet from? Thank you.
@PRHSChemistry We didn't order the magnet. We borrowed it some someone who works here and they salvaged it out of some old piece of equipment that was getting junked. There's a label on it that says it's from GE, but that's about it. The little neodymium you can get are strong enough to do this. Granted, small magnets aren't as impressive, but they're also only a few dollars.
@JeffersonLab And the point is in getting a high density of the field, which is done by using spheres. Neodymium magnets aren't neccessary, strong reaular magnets are just as good if they're spherical.
@endimion17 It should be noted that the spheres in our video aren't part of the magnet. They are just steel ball bearings used to decrease the gap between the poles and to concentrate the field in their region.
1:02 if you look closely not at the liquid itself but at the gas part or the "Smokey" part of the liquid. You can clearly see that it is attracted to the magnet.
@JeffersonLab I want to believe!!!!! Ha ha, probably, or maybe not probably, but ACTUALLY it is spilling onto the ball. I read a study somewhere that atoms were actually found to have had magnetic poles. I love your videos on magnetism, I am a magnetic fReak of sorts. Faraday was awesome, James Maxwell CLerk, Tesla, etc, all my favs. Obviously because I have such an adoration for magnetism. I wanted to ask you if that is in fact true, that atoms have magnetic poles.
@Tenatiouz Atoms don't have magnetic poles, at least, not that I've ever heard of. They can/do have magnetic moments, but that's not the same as having a magnetic pole.
@JeffersonLab I have this speculative "Theory", I guess that would be more accurately called a Hunch, belief, faith, etc. That all things are magnets, and that we are the MACRO organism of MICRO magnetic organism, and through the communicative magnetic fields of these magnets, they send information or speak with one another thus formulating what we think as the human consciousness. Which is what I believe is just all these teeny tiny magnetic forces communicating and sending these to our brain.
@JeffersonLab and from our brain receiving all these communications it manifests from micro communications into the macro spirit or mind or life force, whatever you want to call it. What brings all these things together? What makes matter gravitate into these macro entities made up of many tiny micro entities. It has always fascinated me for years since I was a small boy, and I was just wondering. Does this make any sense to you at all? Or is it just my imagination running wild?
@bloominglove27 Technically, no. At least, I don't think so. Liquid oxygen isn't chemically different than gaseous oxygen, so your lungs should be able to process it. Of course, you'd freeze to death long before drowning ever becomes an issue...
@JeffersonLab You realise breathing pure oxygen is a VERY VERY bad idea dont you? you lungs are NOT "able to process it" Most of the air around you is nitrogen.
@halloforigin I think you may spontaneousness combust though actually, I had friends in a cryo lab, and a vat of lox large enough to drown in creepy... There is something to do with oils and the flash point in a nearly pure o2 environment, basically fuel plus O2 = one step away from disaster. The other thing thought of is ambient temperatures from thermal conduction and how brittle lung tissue would be at such questionable temperatures...
Perhaps someone a little more experienced could expand?
@Fe0n You would get all the other paramagnetic chemicals as well I imagine. Sounds, sound... though I think using the difference in boiling points to separate is infinitely more logical for efficiency reasons.
@Death4life1 In essence, you get liquid air. Take a look at the video we made called 'Liquid Nitrogen Experiments: The Balloon' and you'll see a mix of liquid oxygen and liquid nitrogen.
I think jefferson labs should make a youtube video on superfluidity, demonstrating what it is and why certain matter like liquid helium can enter that state.
@percussionist624 Interesting... I don't think we would be able to demo it, but I can talk with the folks in the cryo group to see if something can be done.
@Daaviator5896 Technically, no. Your lungs should be able to process oxygen in its liquid form just as it can in a gaseous form. It's not chemically different, so there shouldn't be a problem with breathing it.
Of course, you would freeze to death long before drowning becomes an issue.
@iownudie108 Boiling liquid oxygen is warmer than boiling liquid nitrogen. That's why we were able to produce the liquid oxygen in the first place. The actual numbers are 90.2 K for oxygen and 77.4 K for nitrogen at standard pressure.
So if you combine all the gases in air in liquid form could you drink it to get the air you need in your system instead of breathing? If you had enough of course.

I love Oxygen. I wouldn't breathe anything else even if I had the choice.

1:02 if you look closely not at the liquid itself but at the gas part or the "Smokey" part of the liquid. You can clearly see that it is attracted to the magnet.

@Tenatiouz I think you're just seeing cold air 'spilling' on the magnet.

@JeffersonLab I want to believe!!!!! Ha ha, probably, or maybe not probably, but ACTUALLY it is spilling onto the ball. I read a study somewhere that atoms were actually found to have had magnetic poles. I love your videos on magnetism, I am a magnetic fReak of sorts. Faraday was awesome, James Maxwell CLerk, Tesla, etc, all my favs. Obviously because I have such an adoration for magnetism. I wanted to ask you if that is in fact true, that atoms have magnetic poles.
Tenatiouz 7 months ago
@Tenatiouz Atoms don't have magnetic poles, at least, not that I've ever heard of. They can/do have magnetic moments, but that's not the same as having a magnetic pole.

@JeffersonLab I have this speculative "Theory", I guess that would be more accurately called a Hunch, belief, faith, etc. That all things are magnets, and that we are the MACRO organism of MICRO magnetic organism, and through the communicative magnetic fields of these magnets, they send information or speak with one another thus formulating what we think as the human consciousness. Which is what I believe is just all these teeny tiny magnetic forces communicating and sending these to our brain.
Tenatiouz 7 months ago
@JeffersonLab and from our brain receiving all these communications it manifests from micro communications into the macro spirit or mind or life force, whatever you want to call it. What brings all these things together? What makes matter gravitate into these macro entities made up of many tiny micro entities. It has always fascinated me for years since I was a small boy, and I was just wondering. Does this make any sense to you at all? Or is it just my imagination running wild?

@JeffersonLab I would love to hear your response! Please message me back, and keep up with these awesome videos!! I love the braingasms!!!

Can you drown in liquid oxygen?
bloominglove27 8 months ago
@bloominglove27 Technically, no. At least, I don't think so. Liquid oxygen isn't chemically different than gaseous oxygen, so your lungs should be able to process it. Of course, you'd freeze to death long before drowning ever becomes an issue...
JeffersonLab 8 months ago 16
@JeffersonLab Wouldn't the liquid oxygen evaporate very quickly once within the lungs and cause lung over-expansion as well?
StopMotionMind 8 months ago
@StopMotionMind Possibly. Probably the least of your problems if you find yourself drowning in a pool of liquid oxygen, though.
JeffersonLab 8 months ago
@JeffersonLab
Haha yes very true
StopMotionMind 8 months ago
@JeffersonLab You realise breathing pure oxygen is a VERY VERY bad idea dont you? you lungs are NOT "able to process it" Most of the air around you is nitrogen.
AustralianGaming101 1 month ago
@AustralianGaming101 actually, while breathing pure oxygen is a terrible idea, it's not going to kill you straight away.

Just a question what would happen if after making the bridge with liquid Oxygen you poured on the liquid Nitrogen?
TimeTravlersUnited 8 months ago
@TimeTravlersUnited The liquid nitrogen knocks off some of the liquid oxygen. That's what more or less happens near the end of the video.

@halloforigin I think you may spontaneousness combust though actually, I had friends in a cryo lab, and a vat of lox large enough to drown in creepy... There is something to do with oils and the flash point in a nearly pure o2 environment, basically fuel plus O2 = one step away from disaster. The other thing thought of is ambient temperatures from thermal conduction and how brittle lung tissue would be at such questionable temperatures...
Perhaps someone a little more experienced could expand?

so if you cool down the air below the boiling point of oxygenand put a megnet insideyou can get the oxygen out of the air ??
Fe0n 11 months ago
@Fe0n You would get all the other paramagnetic chemicals as well I imagine. Sounds, sound... though I think using the difference in boiling points to separate is infinitely more logical for efficiency reasons.

what happens when you mix liquid oxygen and liquid nitrogen together?
Death4life1 11 months ago
@Death4life1 In essence, you get liquid air. Take a look at the video we made called 'Liquid Nitrogen Experiments: The Balloon' and you'll see a mix of liquid oxygen and liquid nitrogen.
JeffersonLab 11 months ago
I think jefferson labs should make a youtube video on superfluidity, demonstrating what it is and why certain matter like liquid helium can enter that state.
percussionist624 1 year ago
@percussionist624 Interesting... I don't think we would be able to demo it, but I can talk with the folks in the cryo group to see if something can be done.

could you drown in liquid oxygen?
Daaviator5896 1 year ago
@Daaviator5896 Technically, no. Your lungs should be able to process oxygen in its liquid form just as it can in a gaseous form. It's not chemically different, so there shouldn't be a problem with breathing it.
Of course, you would freeze to death long before drowning becomes an issue.

@JeffersonLab how cold liquid oxygen is? i supose it's colder than liquid nitrogen?
iownudie108 9 months ago
@iownudie108 Boiling liquid oxygen is warmer than boiling liquid nitrogen. That's why we were able to produce the liquid oxygen in the first place. The actual numbers are 90.2 K for oxygen and 77.4 K for nitrogen at standard pressure.

why don't you just use your magnet to attract the liquid oxygen directly? magnetism can pass through the test tube.
