Supercritical Fluids are one the strangest states of matter and yet they are found everywhere from Decaf Coffee, to dry cleaning, to the atmosphere of Jupiter. When we think of an exotic state of matter we tend to think of the really weird things that matter can do in extreme circumstances - like how at very high temperatures we get the plasma that the sun is made of, or at extreme densities we get the nuclear matter of neutron stars. But there’s one state of matter - supercritical fluid - that’s not solid, liquid or gas, but is also not confined to extreme or rare environments. In fact, there are planets in our solar system completely covered with oceans of the stuff, and you’ve often been the beneficiary of its powers without even knowing it.

For those curious on triple points, a very tangible example is found in geology. The crystals andalusite, sillimanite, and kyanite are made of the same material. But the pressure and temperature experienced when cooling determines what crystal precipitates. A single chunk of rock can naturally have all 3 types forming alongside each other. It's beautiful.

That isn't a triple point. A triple point is the state in which you can move to any other state, solid, liquid, or gas, directly from that 'triple point. Or are you trying to say that this rock is in a gas, liquid, and solid state?

@TheDaggwood Жыл бұрын

@@pyropulseIXXI My example is a triple point in geologic terms, which is different from a thermodynamic triple point. A thermodynamic triple point pertains to 3 phases of matter existing at a single juncture, while a geologic triple point pertains to 3 different crystalline structures at a single juncture. Yes you are correct in that this video is the "classic" true definition of a triple point, I'm just providing another way of looking at it. A triple point in geology is also a point in which 3 tectonic plates intersect, but I'll leave that out to avoid further complication. They are called triple points because both scenarios involve a substance being 3 different unique phases/materials at equilibrium. Both are rare to find in nature!

It also causes enlarged blind spots, which is a little weird because the brain fills in the missing area so things aren't hidden behind a wall of black, they're just deleted. eg, I walked into a step ladder one night because I couldn't see it, I ran my hand into a table saw because my hand was in a blind spot and I could not see it despite looking directly at the blade.

I learned more about supercritical fluids in this KZfaq video than I did in the year I attempted a physics masters thesis on the stuff. The major professor had tried to record fluid flow patterns of a supercritical fluid, but his experimental setup left much to be desired. The heater was an old fashioned lightbulb, controlled by a laptop and a thermocouple. But instead of putting the bulb in a socket, he had me use a soldering iron to weld the wires to the bulb (?!) (yes, this is a physics experiment). I ended up doing a non-thesis masters.

It'd probably be faster than getting an ophthalmology consult booked for visual flashes too.

@atarahashirazi1941 Жыл бұрын

For anyone who needs to see this if you stayed for the last comments in the video: this is especially true for nearsighted folks with extra strong prescriptions. The more flashes and floaters that you see (they aren't bacteria), if the number goes up a lot, get to the ophthalmologist. If you have a retinal tear, you might see a black 'sheet' fall across your vision or something like that. Again, get help immediately if you want to keep your eyesight. I had a scare once with an aural migrane where I could not see for the first time. It was terrifying, but fortunately temporary. I thought my retina tore because a doctor had warned me that with my prescription that could happen to me. Also, I'm not a doctor. FYI.

Amateur Naval Historian here: This video is great. I've always wondered about the difference between standard steam and supercritical steam. Prior to the invention of reliable diesel nuclear reactors, the largest ships used oil fired boilers. Spray oil into a firebox and ignite it to biol water moving through tubes. These boilers turn water to vapor steam and, due to thermal expansion, the steam increases in pressure and can be used to run steam pistons or turbines. Basically, it's an oil power plant or steam train being used to run a ship. Nuclear reactors run much hotter. The reactor is hot enough to increase the temperature and pressure enough to make the steam supercritical. If supercritical steam is incompressible, then you don't lose as much energy throwing it through the steam turbines. I think. Maybe. Maybe Matt can confirm or debunk? But that's my conjecture based off this.

Sooooo… could particles that are usually considered metallic stay as such in the supercritical fluid phase, like say mercury, iron, lithium, copper just to name a few, and how would their properties typically associated with metals change, would they still be electively conductive, could they still be magnetically attracted in some manner?

@ericdiederik3732 Жыл бұрын

Interestingly, metals exhibit what is considered to be in plain terms 'metallic' behavior' exactly because the the properties they have when solid. The nuclei of metals can easily part with one or more of their outer electrons which allows them a degree of freedom in a crystal lattice. This is what makes solid metals conduct electricity. To answer your question: Metals techinically do not conduct electricity in both critical and non-critical gas forms. They are however readily ionized allowing a current to flow through a path of plasma, in what is called an arc discharge.

@@ericdiederik3732 ok, so most typical metals at room temperature and atmospheric pressure, when undergoing super-criticality, behave closer to gases than they do as liquids or solids? That’s what I thought, but I could never find any research, resources, or references to check if that idea was the case or if something else was going on. I knew that the comparatively higher density solids combined with the fact that most of the metallic elements easily loss or give away electrons was the main reason that they could conduct electricity (very over simplified, but you get the point) and I was wondering if the density would be high enough for supercritical fluid “metals” to conduct electricity in a similar fashion to solid or liquid metals. Thanks for the comment, I’m going to continue to search for information on this very subject

I was born in 1989 and have always loved science. Grew up watching Bill Nye and every physics based show Nat Geo or Discovery Science channel could throw at me. In my entire life no one has taught me more or helped me understand physics and our universe more than Matt Parker. His dedication to teaching and explaining physics is truly an inspiration to me and will always bring me back, eager to learn more new things. Thank you for all the great work you do!!!

This is so refreshing to hear you speak about classical physics at the edge of our knowledge (or our understanding as laymen) rather than almost speculative knowledge at he edge of our fondamental non clasical knowledge (even if I love that too!). Continue spicing your more extreme things about space time (which are great!), with sometimes (just sometimes) a detour to more classical physical mysteries : the three bodies problem, the Navier-Stoke equations, chaos theory, matterial physics on the macroscopic scale (properties of solids : physical, electrical, chemical, magnetic, etc.). Don't lose the space-time trend : just spice it with videos like that which are very educational and interesting when you present them this way, with your talent. Go on doing it in your own very subtle way, your serialized way, to fascinate the non geeks who are afraid of equations and the very geeks who want highly complex physics without them. I think I'm a fan because I'm a bit of both. Thank you!

17 years ago, in a skyscraper near a river.. I was supposed to be working on the 33rd floor but I was exploring around whatever floors my keycard gave me access too. I soon found myself on the roof on an outdated observation deck. It was really cold, like -20°. I noticed that I was eye level with the fog coming off of the river and the surface was reacting like the surface of a body of water. There was fog waves. Man I miss those days.

~ I attribute the properties of a supercritical fluid to convection, which affects only liquids & gases, along with additional interesting control conditions that can be explained by radiation in a vacuum. ~ Thermal conveyors = conduction (solids), convection (liquids/gases), radiation (vacuum). ~ A plasma condition is the intermediation between an inert gas & a vacuum borderline transformation, caused by radiation.
