@@user-monkeys liquid oxogen is incredibly cold - 118 C° or -180.4 F° and cryogenic liquids cause burns yes that’s right freeze burns sound strange but it’s true. If you get splashed with a cryogenic liquid like Lox (liquid oxogen) or liquid nitrogen (even colder) which I’ve had the pleasure of been burnt on the back of my hand by a colleagues accident it causes blisters after it unfreezes in a few seconds. It might take a little longer with Lox but it will certainly give you freeze burns so it’s not a good idea to get cryogenic liquids on bare skin. Hope this answers your question.
@@7th_Sunrise yes, along with one of a few types of fuels including kerosene (historically very popular), liquid hydrogen (theoretically most efficient and what the space shuttle used during launch, but a massive pain in the ass for tank design), liquid methane (rapidly becoming a popular choice now, although it requires stricter care to avoid spilling it or venting it without burning it first since it's worse for global warming than than CO2). Another example is ethanol (eg the v2 rocket) but it's not very popular anymore.
The reason that it is paramagnetic is because oxygen molecule has two unpaired electrons. Electrons not only go around the atom in their orbitals, they also spin, which creates a magnetic field. Unpaired electrons spin in the same direction as each other, which increases the magnetic field effect. Hope this explanation helps.
I worked at a WW2 era steel mill. The vintage instrument used to check exhaust oxygen in a huge furnace used this principle, as gaseous oxygen acts the same way.
-297 degrees boiling point will melt your lips, tongue and throat off, I work with this stuff daily and its crazy to see this dude just pouring it out, its very reactive and if it mixes with hydrocarbons that little bit can create a fireball the size of a prius
@@FirstMomentsOf Hi bud, this is a common misconception. Once we draw the molecular orbital diagram, we can observe that, oxygen has 2 unpaired electrons in the anti bonding orbitals. Hope this helps 🙌
@@lenarianmelon4634 Maybe that stupid AI would quit yelling about Oxygen if I was in a sea of it. The liquid oxygen in this video is clearly different than water.
I love watching these. Things have really come a long way. Like time lapse. We had flowers that every night everyone sat in our yard to watch our flowers bloom. In the morning they died. 😢
no shit sherlock! explosive stuff btw! my uncle used to transport all that stuff at Air Products, truck driver! scary job Id think, especially in RECENT times! everything more prohibitive to the risk danger factors! bummer!
I learned about that in litteral high-school. I don't know what grade that translates to in terms of American classes (with the numbers and all), but yeah I didn't have to wait for college to learn about that).
Back in university we did an experiment that involved liquid nitrogen, methane, and oxygen, and the class goofball accidentally tipped the tank containing the liquid oxygen over, spilling around 15 gallons of the stuff. We all had to jump onto the lab benches to avoid getting frostbitten, and we had to call the lab tech to cut the power because we don't need the sparks from the lights igniting in this oxygen-rich environment.
Oxygen has a very low boiling point therefore its a gas at room temperature, if its cold enough it wild go to liquid similar to mist condensing on glass. Although i wonder if it goes solid if cold enough. (basic chemestry)
According to MOT, nitrogen molecule has 14 electrons, making it a diamagnetic molecule, thus it doesn't have any effect of magnetic field. Oxygen molecules on the other hand has 16 electrons in total, thus they're paramagnetic and the unpaired electrons in oxygen molecules interact with the magnetic field, helping form the bridge. Thanks for sharing such amazing practical aspect of the concept ❤️
this guy obviously had everything around there very carefully degreased. and one training film I saw a guy had put one drop of WD-40 on a valve then wiped it off. when he closéd the valve after the tank was filed with oxygen the whole thing exploded. a charcoal for cat soaked in liquid oxygen has approximately the same explosive force of a stick of dynamite and can be set off by dropping a marble near it not on it just near it.
I just learnt that oxygen was magnetic which i should had known since i had toy magnet things i played with as a kid since robotics got a bit old(dads old toys) i learnt to use the magnets to charge the robotics kit though so that was cool, just not this cool.
@@residentboejiden5796 how does having a toy magnet thing as a kid mean you should have known liquid oxygen was magnetic??? i dont understand your logic there
Oxygen is paramagnetic as it has unpaired electron in its 2p subshell. Nitrogen is diamagnetic (that is it doesn't get affected by magnetic field) as all of it's electrons are paired. Hope this helped you!
The reason this happens is because molecular oxygen (O2) is paramagnetic, meaning that the unpaired electrons share parallel spin. What’s cool is that water (H2O) is also influenced by magnetic fields, but this time, because the molecule itself is polar. (Oxygen and hydrogen having different electronegative values, making the oxygen side of the molecule negative and the hydrogen sides positive)
@@castleanthrax1833 correct, I was thinking of which polarities influenced them, not their actual charges. I’ve corrected my original comment to reflect this.
fMRI's do this, they're like normal MRI's but completely different because they map blood flow using the magnetic properties of oxygen. Really useful for imaging the brain and being able to see brain activity via the varying oxygen levels after neurons fire and stuff
O2 has unpaired electrons when you draw out it’s molecular orbitals. Unpaired molecular orbitals means that the substance will be paramagnetic and interact with a magnetic field. N2 has only paired electrons in its molecular orbitals (diamagnetic) and makes no such interaction with the magnet.
Can we say almost all (not absolutely all) molecules with unpaired electrons in their outer orbital, are paramagnetic and also those with paired outer electrons are diamagnetic!? Thanks in advance 4 reply
@@shahriaralmassi7086 so molecules with unpaired electrons in the outer shell are known as free radicals, and these molecules are paramagnetic. For example, if you had a bromine radical it would have an unpaired electron in its valence shell and would be paramagnetic. However, free radicals tend to dimerize, in this case bromine radicals dimerize to bromine gas (Br2) when the single electrons converge to form a bond. Because these electrons are now paired, Br2 is diamagnetic. The interesting thing about liquid oxygen is that it is paramagnetic in the diatomic state. also i’m not by any means an authority on this stuff, just an undergraduate with a passion for chemistry. anyone who is of greater expertise who reads this please feel free to make any corrections and other amendments.
@@TheMilwaukieDan this is an interesting question that I do not have a great answer to. From what i’ve read looking into this there isn’t much of an effect but the answer is probably best left to the physicists of youtube.
Medical sensors, like finger tip pulse oximeters, use specific wavelengths of light and measure the amount absorbed to determine the amount of oxygen in blood. MRI and fMRI machines can detect blood oxygen this way, but the far more common method is using light. Source: I work for a medical device company.
💚 Light Should Be Used To Power All Craft, Vehicles, Machinery, Technology, Homes etc & Not Just The "Suns" Light....Also The Møons Light 🤔😉 Much Love 🕊
Oxygen is normally paramagnetic, so when cooled enough it gets an hysteresis curve. If you could put the magnet inside a liquid oxygen tank and keep the temperature you could see the field lines
@@SaRaSin712 In a way. I'm not sure I'd use the word "fall", though, that implies there's a down. It's.. more like a cascade of outward motion in all directions. When Mars lost it's atmosphere (or, well, had it severely weakened), solar rays were able to more effectively penetrate the surface of the world, and the contents of that atmosphere changed simultaneously. This raised the surface temperature of the world (with the pressure differential that came with the lowered atmospheric density) to a point that water sublimates from ice to vapor, and vapor to ice upon contact with either the surface, or the subterranean layers. And with no atmosphere, the water vapors kind of just.. Left orbit. Turning into ice in space, and ending up who knows where. So, TECHNICALLY.. the atmosphere holds it down. But with gravity being what it is, if the conditions for the water kept it either liquid or solid, it would likely remain on the planet for quite some time. Either due to being unable to move (solid), or holding itself down under it's own weight (liquid). TL;DR Technically yes but no
Superb ! Everything that can change its shape, if left free uninterrupted by any outside force: it ends up spherical or rounded in shape. ( rain drops to lava ropes and pillows )@@SaRaSin712
Testing for oxygen content in blood is great, but antigravity gyroscopic technology trumps that in a heartbeat.This is Massively important science for future tech projects and reaching the next major technological leap forward. This is space engine stuff here.
Me drinking liquid oxygen: *sip* My body: WHAT THE F*CK edit: MOM IM FAMOUS edit 2: stop saying cring I only did it cus I couldn’t think of anything else
@@NicholsKT well the boiling point is so low for oxygen(-183 Celsius, -297 Fahrenheit) that you would severely damage your body and die. Now if we somehow could drink it, I’m not sure I assume it would be fine, unless it’s too much oxygen into our body then we die from that!
@@NicholsKT you would suffer severe internal damage because the liquid is cold enough to form ice crystals inside your skin pretty fast, everything it touched on the way through would be freeze burnt and also you would probably get bloated or burp a lot because of the expansion of the gas once the oxygen heats up from your body.
I think what actually happen is the liquid touches edges of magnet and due to temp diference it starts to boil producing gasees and bubles that form kind of a barrier btw 2 sides of magnet.
@FrogeniusW.G. So for something to exhibit magnetism a species needs unpaired electrons. Both species are diatomic which means O and N in their elemental states are actually O2 and N2. When two atoms bond together all of their atomic orbitals join together and form molecular orbitals which are arranged differently. In nitrogen the highest occupied orbital is alone on its energy level this means that 2 electrons fill up the orbital at the same time. In oxygen the highest orbitals with electrons in them are on the same energy level. This means that they get simultaneously filled. As electrons fill empty orbitals before pairing up. Therefore we have 2 unpaired electrons which cause magnetism. If you want to visualise this look up on google images "Nitrogen M.O. diagram" and "Oxygen M.O. diagram" Source: I have a bachelor's degree in chemistry.
So what, we all know that oxygen is paramagnetic due to single electrons in 2π orbitals and thus will be weakly attracted to magnetic field. Just the basis of Magnetic Orbital Theory.
I love that you explain the science and then how we use it in modern society. I find one of the biggest things they forget about in school when they teach you about science is " why " how is this applicable in my real world? Makes it much more memorable. Love your videos
Now that same phenomenon drives our atmosphere. Strong magnetic anomalies have the ability to move cold air. I've tracked cyclones and spontaneous heavy misting events that are closely linked to prior seismic activity in the area.
@@alexho2304 it is proved Search prof. Walter Levin 's video of magnetism. He did this experiment and gaseous oxygen didn't stick to the magnet, let alone the liquid oxygen
@@alexho2304 firstly i would like to state that water being not a paramagnetic is not my claim, My claim is that gaseous and solid oxygen would not stuck inbetween the magnets
@@alexho2304 ok Alex, In my experience, the gaseous oxygen didn't stick, however i am eagerly willing to correct my mistake and expand my knowledge Thanks for letting me know this Have a great day
