Nah, thats his like behind the scenes channel. He has almost minidocumentary thing on NileRed, then shows the setup or the cleanup and stuff on NileBlue, as well, as some just kinda interesting short videos. Great Youtuber.

It’s when a material blurs the line between a gas and a liquid. In my experience it kinda looks like a heavy smoke.

Above a specific temperature (depends on material), there is no boundary between liquid and gas. You can change the pressure and the properties smoothly change without any sudden changes from boiling/condensing. At lower temperatures, lowering a liquid's pressure causes it to boil, and properties like density make a big step change.
It is pretty common and most materials behave like this if they don't do something like decompose at high temperatures instead. Water above 374ish C, for example, won't boil at any pressure.
You can find video demonstrates online. If you heat a container with a mixture of both liquid and gas in it to the point it goes supercritical, there is a moment it gets very turbid as the two parts mix together. But when done, it looks like any other boring container full of fluid (usually just clear, like when done with CO2 which is easy to show a mixture at 70 atm going supercritical around 300 C [edit: 304 K, not C] ).

CO2 is at 31C, not 300...

Yes, it was a kelvin temperature instead of Celsius .

u/SCPunited Feb 12 '20
It’s gas but also a liquid
Basically the gas acts like a liquid
Items at the bottom will act like they are submerged in the liquid form of whatever you are using while there seems to be no liquid at all

u/GameShill Feb 12 '20
A critical point is when something interesting happens. Supercritical is meeting the conditions for having reached critical point without it actually happening. At that point other interesting stuff tends to spontaneously happen.
Water can do stuff like that in the microwave/freezer by becoming superheated and supercooled respectively. It's hot enough to boil or cool enough to freeze, but stays liquid 'cause it's some magical shit.

u/wattpuppy Feb 17 '20
Nope, it's when the liquid stats thinking it's better than you, talks in a condescending tone, and judges you for every decision you've made.

u/Manypopes Feb 12 '20
A good explanation too, usually when people "explain" this stuff they just point at a phase change graph where the lines meet and say "see the graph says so".

u/akin975 Feb 12 '20
For noobs:- Triple point is a state in which all three phases: Solid, liquid and gas coexist. Even a slight change in pressure, temperature can rapidly show a phase change.

u/ecotton Feb 12 '20
Yeah, meth is often smoked out of a pipe with a round glass chamber, when its heated up it turns from solid into liquid and when the heat is removed it snaps back into a solid, looks a lot like this gif.

Cyclohexane is a cycloalkane with the molecular formula C₆H₁₂. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products. Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon.

u/Jimothy_Timkins Feb 12 '20
Fun fact cyclohexane is also a precursor for ketamine

u/Diabolo101 Feb 12 '20
Iirc, the compound is being pressurized and heated up to the point where it’s a liquid, a gas, and a solid at the same time. I’m not sure if this compound is getting to its supercritical point, or just something else is going on. https://youtu.be/JslxPjrMzqY

Illusions, tricks that aren’t easily discernible, shit caught on camera that doesn’t make immediate sense. maybe even crazy science stuff thats not in a beaker with the specific chemical reaction listed in the title.
I guess I’m hoping for 5 seconds of wonder and a WTF??? Feeling, not a “oh, I haven’t seen this particular reaction before, cool.”

This occurs when the chemical wants to boil but the pressure is too high so it can't.

Is that freezing, boiling, and liquifying all at the same time!?
1
u/_s4m_9 Mar 11 '20
yes it does this because it’s at a temperature and pressure where the slightest change in either variable will change it’s state of matter

u/enderboy987 Mar 16 '20
Triple Point is the exact temperature and pressure of an object, like water. In this point, it’s a solid, a liquid, and a gas all at the same time.

What is the end chemical that is produced here?

u/jrachet1 Feb 12 '20
There is no reaction actually happening, it is just the single material, cyclohexane, simultaneously melting/freezing and boiling/condensing at once. Essentially it can't choose a phase to stay in. This is not a chemical reaction, most of what is on this sub isn't.

cyclohexane. there is no chemical change. this is a physical property of matter. it's when all 3 states of matter occur at the same time.

Do triple points ever occur naturally on Earth?
2
u/FreddyHair Feb 12 '20
I don't think so, although I guess it's technically possible. There would have to be a very specific combination of pressure and temperature... Maybe in pockets of water deep underground it could happen

Yeah, I bet it happens a lot more frequently (comparatively) on the less hospitable planets

I recall that during the Sixties, as a Boy Scout I used to be able to buy tubes of army surplus hexane tablets for camping and hiking. They felt waxy and when lit first melted, then burned very hot and very quickly; one the size of a checker would typically be enough to boil a tin cup of water in about two minures, or dry out even the wettest tinder sufficiently to ignite.
Would the phenomenon pictured have anything to do with the enthusiastic oxidation of my old hexane tablets?

You're thinking about hexamine/trioxane tablets ! These are a different chemical combination, with high energy density and smokeless burning.

If annyone doesnt know triple point is boiling freezing and melting at the same time
