  • i think the blue color of oxygen is beautiful

    but im 65% oxygen so i might be biased

  • is O2 highly paramagnetic???

  • This was SO cool! :0

    I literally was left speechless!

  • Is it possible to separate oxygen from nitrogen by an electromagnet? If two test tubes joined together by a capillar or straw, with one of the tubes surrounden by a copper coil as an air core solenoid. Will the solenoid tube be filled with oxygen while the other one with nitrogen?

  • the rest is other chemical elements. Todays world population is in excess of 6.5 billion. Although the natural electrolysis of water by the world's thermo reactrive processes decomposes water and replenishes the oxygen, this process is rather slow. On the other hand we are continuously exploiting iron ores as well as other metals that oxydize and retain the oxygen atoms. Think abvout it Bob; I see that you are a bright and knowledgeble person.

  • @jqs1943 Seriously? Seriously? Dude you are omitting large portions of the O2 cycle. Take a class on atmospheric chemistry please. O2 is on the decline, just as CO2 is on the rise, but these are minute changes on the order of ~10^-3 (per 5 years), not even including the replenishment cycle from things like Photosynthesis. Your 60 year old data definitely needs recalibration. Heck you probably think 'bleeding' is still an accepted medical practice.

  • @chiagirl bleeding.....maybe for high blood pressure.....and if dying isnt the sort of thing you worry about....

    gave me a good laugh....

    peace......

  • @jqs1943 yea well what you dont account for is that with the increase in the emission of CO2, plants will absorb more CO2 and produce more O2.. simple chem bro.

  • We're attracted to the electromagnetic fields of extremely high voltage as a piece of iron is attracted to a magnet. We are depleting earth's oxygen level and it's reaching a critical level for the sustainment of life and the well being of healthy lungs.

  • @jqs1943 We are NOT running out of oxygen. Where did you get this crackpot theory?

  • @ediblebatteries When i was a youngster in school, i remember that the oxygen level reported was 33 % oxygen and 66 % nitrogen with a 1 % of other iompurities. Now it's reported that the oxygen level is only 21 %

    do the research and you'll see the numbers.

  • @jqs1943 It is true, oxygen is converted to carbon dioxide in combustion reactions, but having lost 36% of our atmospheric oxygen in the last 150 years is absurd. A quick 5 minute internet search yielded an article reporting a loss of 0.1% oxygen since pre-industrial revolution numbers. I think the difference you're talking about could be from different methods of detecting atmospheric concentrations of oxygen or inaccurate instrument calibrations.

  • @ediblebatteries You'll need to dig a little deeper to find the values that i'm talking about. In order for me to make others understand why the oxygen volume in the atmosphere might have diminished or is diminishing is a rather complex explanation that requires more than 400 characters as is alotted to us by u tube under comments,but consider this reality; i was a student back in the 1950's. the world's population was slightly over one billion, a person weighing 180 lbs. is about 125 oxygen and

  • thats amazing but whats even more amazing is the fact 4 people accidently miss the like button.

  • Hard to believe, Liquid oxygen o_O

  • Woot I have just been part of your class for 5:20 min :D I am truly grateful :)

  • is oxygen gas magnetic, should see what happens if you put rare earth magnets in a respirator.

  • Before you ask....No you cannot breath it......

  • This also makes me seriously think and wonder if this is even a sliver of a clue towards solving the infamous "cold fusion" legend. I mean, electrons having an interaction with a force that isn't high temperature affiliated. If these paramagnetic electrons can be forced, with enough magnetic energy, to fuse with other atoms or electrons...

    Im probably way off and not taking something into account. Its just a hypothesis coming from a person with very basic knowledge in this field.

  • @Mastermind8908 Hmm... What is temperature, it's closely related to the average speed of the atoms and if the substance is initially cold and you push atoms together with high magnetic filed they will start moving faster, hence they'll become warmer... You'd then have to apply enormous magnetic field for the atoms to gain enough speed for a nuclear reaction of some sort to get initiated by that time it's not going to be cold by any account :)

  • Im not a student of chemistry but Im gonna give this a shot. As he pours the Ni on the floor and inhales the Oxygen, he says its fine because we breath it. But we breath a balanced amount of these elements. So isn't it a little hazardous when one is exposed to more Ni gas then O or H; like a person with nitrogen narcosis has a higher level of Nitrogen in their blood? And close exposure to pure Oxy gas would cause one to pass out, right? Not to mention the fact that its super cold.

  • @Mastermind8908 Astronauts breathe (or at least they used to at some point) pure oxygen in their spacesuits and spacecrafts. The health of an astronaut is very important, so I don't think they'd let them breathe oxygen if it was bad. Nitrogen is different because it is inert and doesn't do anything including supporting human live, unlike oxygen. So too much nitrogen CAN be bad, but not because N2 is toxic or smth, it's not, but you do need O2 to stay alive :)

  • hi, i m from Japan

    we did this M.O in 7th standard in middle school

    i want to thank you for letting me brag about myself.

  • @zoriano88 you're not gonna believe this but when I took 3rd year (university) mathematical physics in the first lecture we were taught what's a vector, what's a dot product and so on, things we covered a long time ago, just like you, in school. Yet things got "a bit" more complex (actually complex analysis was also there, no pun intended:))) rather quickly :)

  • @zoriano88 But I would have to agree that there are many things which we should have covered way earlier... And that's a bit of a problem right now, courses get "dumbed down" and there's no way around of admitting it. Only those who really want to study go to the library and get the material they should be taught.

  • so in a low O2 environment i can hold a powerful magnet to my mouth and be able to breath?

  • I have a question: What would happen if we got to breathe in 100% oxygen

  • @TheKljovoReloaded we would die because the air we breathe only has 20 percent oxygen alone

  • hi,i m from India.

    we did this M.O. in12th standard in high school.

    i want to thank you for these educative videos.

  • cool! the lox is boiling! :D

  • cool!

  • it's blue, for the same reason you see in a nuclear reactor core?

    or is that something else?

  • @MrCedal No, that's completely different. First, the blue color you see in a nuclear reactor is a glow, while there's no glowing here, just light being reflected. Second, the glow of a nuclear reactor core is Cerenkov radiation (emission of light when a particle, placed in a certain medium, moves faster than light does in that medium), while all that's going on here is absorption (frequencies of red, yellow and green are absorbed and the rest is reflected).

  • @DevilMaster You are right,what was I thinking xD

    Didn't listen carefuly enough.

    Sorry for that, and thanks for explanation!

  • so, O2 is a true ferromagnetic fluid?, like the magnetite powder in oil but true

  • @ampeyro

    Paramagnetic, it conducts an electrical current that resists the magnetic field. Thus it doesn't like to move when it's in a strong field. Get a copper bar and a super magnet and try rubbing the magnet on the copper as fast as you can (or vice versa) and you'll feel it doesn't like to move.

  • @Zappyguy111 i didn't understand the images(the zoom isn't so good), i know what paramagnetism is and to experiment it a copper barr isn't enough, a tube works better

  • @amperyro

    A tube works just as well, but the idea of a bar is that the current flow in circles on a plane perpendicular to the moving field thus by using a bar you can dramatically reduce the resistance thus increasing the opposing current with the available EMF thus increasing the opposing field. But liquid oxygen is not ferromagnetic, it is not attracted to a magnet and it conducts electricity very well.

  • @Zappyguy111

    Just adding on what I've said, (prior to my now scared memory of the magnets... I WARNED HIM THEY WERE STRONG DARN IT!!!! BUT HE DIDN'T LISTEN... ; ^( ... ) I always used to pull out my 2x1/4 inch copper bar and rest a 50x10x20mm bar magnet whiles the bar was vertical and let the magnet tinker it's way down the bar. It amazed everyone!

  • Oops - Paramagnetic="Opposite to magnetic"!

  • @hux2000

    Like an MRI !!! No ferro- or electromagnet there!!! Just a giant perfect conductor (paramagnetic material), Yttrium barium copper dioxide! (WOOT!!! I REMEMBERED IT!!! Thank you spell check!)

  • Magga

  • wow, cool :D

    5/5

  • I can't wait till college.

  • It's not as fun as it seems. Enjoy the time you have left before you have actual responsibilities.

  • this is true

  • Let us hope the world bankers don't find a way to magnetically control our oxygen, because their vision is to have us pay to breathe.

  • To Brianinski : They are already making us pay for exhaling (CO2 emissions), so why not for inhaling too?:) Seriously, though, the eventual applications of paramagnetism could be in information conservation and transmission...

  • Thanks! I was studying fxn of cytochrome p450 and paramagnetism of O2 plays a big role. So i needed ththis for my understanding.

  • I have quick question, seeing how this is liquid oxygen, would drinking it when you need air like underwater do what I'd hope it would do? This of course doesn't take in account the extreme temperature but I'm curious.

  • It would freeze your insides, it would never reach your lungs, and as it expanded it would pressurize you from the inside. You would die. Period.

  • Thanks, air as a liquid always made me curious, I'm not a chemical expert though.

  • Reminds me of a Movie i saw once. They used some form of liquid air in a diver suit to go to high depths in the ocean... Obviously compleat bull crap, but it's cool to mess around with physics in you head to see how things would be different

  • Actually, it was real, the whole scene with the rat in the fluid was real, however, it wasn't liquid oxygen, it was a perfluorocarbon. The Abyss has some basis in practical application of this breathable liquid, however, there are some hurdles, for one, it would be too much of a strain to just breathe the liquid, it must be assisted, due to it's viscosity. The diver would have to breathe harder. Also, CO2 doesn't really go into it very easily, so getting rid of CO2 in your body would be hard.

  • The benefits would be an excellent way to protect divers from pressures of deep water diving, and protection against decompression sickness and complications. It would be practical, if those small hurdles can be bypassed.

  • That is one pretty incredible comment. :)

    Thanks for this video. Very helpful.

  • @robertburkottawa but what if the oxygen is not cold but just pressurized to become a liquid so its temperature will remain the same and if you are very deep in the ocean it wont expand so much in your lungs to cause damage?

  • @robertburkottawa your dumb. navy seals use this for that exact reason

  • @sodacan187 instead of drinking liquid oxygen why not breathe it???

  • @TheArmo1

    Start breathing oxygen? That's is probably a good idea I'll do that now lol.

    *turns off liquid oxygen and turns on gas oxygen*

  • @sodacan187 Aka Its Pressurized O1 Atoms combined with Ur238

  • @sodacan187 If you drink it it would be in liquid form and go into your stomach, and just cause you to belch.

  • If you had a super strong magnet though like >1GT or something would it be possible to make that "sucking effect" like wind or large vaccuum cleaner?

  • awesome demo

  • i never wudda thought oxygen to be magnetic

  • From Wikipedia: Triplet oxygen is the ground state of the O2 molecule.[9] The electron configuration of the molecule has two unpaired electrons occupying two degenerate molecular orbitals.[10] These orbitals are classified as antibonding (weakening the bond order from three to two), so the diatomic oxygen bond is weaker than the diatomic nitrogen triple bond in which all bonding molecular orbitals are filled, but some antibonding orbitals are not.[9]

  • In normal triplet form, O2 molecules are paramagnetic—they form a magnet in the presence of a magnetic field—because of the spin magnetic moments of the unpaired electrons in the molecule, and the negative exchange energy between neighboring O2 molecules.[11] Liquid oxygen is attracted to a magnet to a sufficient extent that, in laboratory demonstrations, a bridge of liquid oxygen may be supported against its own weight between the poles of a powerful magnet.[12][13]

  • At the end, you need to show the powerpoint slide the professor switched to.

    Otherwise a very excellent video.

  • nitrogen is actualy -320 deg f

  • metric system douche

  • From Wikipedia under Nitrogen: "At atmospheric pressure molecular nitrogen condenses (liquifies) at 77 K (−195.8 °C) and freezes at 63 K (−210.0 °C) into the beta hexagonal close-packed crystal allotropic form. Below 35.4 K (−237.6 °C) nitrogen assumes the alpha cubic crystal allotropic form. Liquid nitrogen, a fluid resembling water, but with 80.8% of the density (the density of liquid nitrogen at its boiling point is 0.808 g/mL), is a common cryogen."

  • My prof did this in my chem lab today!

    Didn't get to see it up close as this video. This is cool

  • that was fantastic. Thank you for a great demo

  • So it is oksygen in the air that "conducts" the magnetic field around and inside an electric reel? Though, very weak.

  • L2 Spell.

  • im thinking about pursuing two different thing in life. Music or Physics

    Any suggestions?

  • Why do you need to limit yourself to one field? Why not both? You have your whole life.

  • sound/audio engineer;)

  • whatever your better at

  • you're

  • i dont care

  • I am in vacuum Engineering and Cryogenic is definitly my favourite lecture unfortunately we haven't got such a crazy teacher, can't wait to do the cryostat laboratory

  • very smart guy

  • In theory,can we use a very strong magnetic to seperate oxygen and nitrogen in air?

  • I dont think so, Ive heard that oxygen is magnetic only in liquid form. But Iam not 100% sure

  • @reseth I think also in solid and gas phase. The effect is due to the electrons in the last orbital so I expect it to be paramagnetic in the 3 phases.

  • Distillation is enough.

  • u can

  • @b43e65f77 That's what I was thinking. I'm sure it is possible to increase the % a little.

  • Physics is so dam cool! No pun intended. I learnt something new too.

    I want to go learn about super conductors and stuff now too.

  • learnt

  • i used to work for praxair in a division of cryogenics.

  • i wish my chem prof was that cool

  • I want to see what you do with the steel wool!

  • I think I'm up to like three brain cells now.

  • Very nice presentation! Keep up the good work.

  • I want to go to this college!

  • Carleton University

  • That's a pretty amazing shirt, Prof.

  • you guys do MO theory in first year at carleton?

  • You bet. Quality education.

  • We're doing MO theory in first year at Stony Brook University too (in the State University of New York system), but unfortunately my class is in a general lecture hall with 500 people in it. Your video was very helpful. Thanks so much :)

  • No problem. My class is 589 students!

  • He's so much better than my drab and monotonous chem lecturer

  • epic what happens if you inhaled liquid oxygen would you drown????????????

  • You might explode. Remember how the guy said, it's 4,000 times denser than gas oxygen?

    Well, the liquid you inhale would expand about 4,000 times.

  • you wouldn't explode actually you probably would probably freeze though besides your body would be absorbing it cause its is oxygen right? and heeeeyyy if you put that in an oxygen tank couldn't you fit waaayyy more in it since its so dense then you could stay under water longer ^_^ well as long as you keep it cold

  • Well, I supposed if you "inhaled" the liquid oxygen, your body would absorb it... but I don't think it would absorb that fast, your body can only take in so much at a time.

    it would probably just expand so much you would just exhale it all really fast.

    if you swallowed it though... that's when you'd probably explode, or have really bad gas.

  • nah, it'd probably burn (freeze) away at your throat like acid... oxidization.

  • I think you first get to freeze yourself and then explode!!!

  • There would not be an explosion gah

  • good teacher

    cool property

  • dude...where are these teachers at....I always was bored in chemistry!!

  • bravo! does this explains the need for iron in our body for enhanced transport of O2 to all cells...?

  • is that y the sky is blue?

  • Great video!

  • Cool prof!

  • this is awesome

  • love chemistry...

  • haha... 2 electrons 1 proton !

  • ...photon

  • This explains why iron in the blood is so important for oxygenation. Thanks, fascinating video and explanation, enjoying all of your videos

  • What a cool demo and professor :-)

    Ive got to do my PhD in Canada ;-)

  • cool

  • can you drink liquid oxygen?

  • if you want to die.

    it's at -192*c

  • sorry i meant −182

  • instantaneously freezes your insides on contact and with contraction of muscles you crack your insides and die lol

  • wahahahaa.. it wouldnt even get to your insides.. just freeze your throught shut.. :P

  • that looks like magnetic water =D

  • wish my chemistry classes would be like that !

  • let me get all geeky on this one this is SO thight, as a matter of fact, I find the paramagnetism of liquid O to be highly amusing, entertaining, impressive, and extraordinary!

  • This is so cool. I just learned something.

  • Wicked, Im gonna go take some Physics and chemistry papers now :)

  • haha i wish i had a teacher like that :p

  • THANK YOU for contributing something worthwhile to Youtube. Videos like this are rare around here...

  • dude really post more vids of this guy... or you if thats you, cuz some of these are really interesting

  • I THINK THIS IS KINDA COOL!

  • Great demo! My chem prof. once put a balloon in a foam box of dry ice to demonstrate how the air in the balloon contracts and expeands the moment he took it out of the box...some of us were just staring at the box of 'fuming' dry ice the whole time, lol!

  • SO NICE

  • that teacher is so cool

  • Fascinating demo!

  • I wish they showed us this in our class.

  • Thx!

  • amazing! what university is that? is it a chemistry class?

    Thanks you

  • Carleton University, Ottawa, Ontario Canada. First year General chemistry class.

  • Hey sweet... I was looking a video of this for awhile, since I saw a picture of it it in a my Chemistry book.

    Thanks!
