- เผยแพร่เมื่อ 1 ต.ค. 2024
- This experiment demonstrates the triple point of a substance. Watch how water behaves at the triple point where it co-exists in solid, liquid and vapour form. There is also a short description of where the triple point lies on a P-T-diagram.
Created by mechanical engineering students and the Centre for New Media at Bergen University College, Norway.

I'd never seen the triple point of anything before ... this makes it so much more concrete!
yeah i thought it was like blue ectoplasm that climbs walls
@@corlfranco9371 You mean like super liquids?
It's not concrete, it's water
its also a gas and liquid too
fau kauf mate
Thank you, please make more video. Don't listen shit like "you're too boring", this dudes needs vsause. It's university level, they don't need it. You're making real good academic experiments with great academic explanation, thank you.
Paolo Vallejo I read your comment with a thick Spanish accent.
Alex Ivanov honestly, I'd say it's not boring enough. Understanding the theory and math behind this is where I'm at.
"it's university level", dude, don't you think knowlegde should be available to all? the way the guy explains makes it boring, but that doesn't mean it is. i think he should improve his communication skills, so more people would be interested in what he has to say and as a consequence everyone can learn :)
just because it's "university" level doesn't mean it has to be boring.
And also, the theory and math behind it as complicated as it can be it is never boring.
University level? This is middle school dude (from an european pov)
Sometimes we need something like this to understand some topic, i always imagine every chart or diagram but it´s awesome to see what a chart says. Thanks for the explanation!
Wow thank you so much. Makes Thermodynamics even more interesting
Is thermo interested ever 😂
@@surajraishwal yes, I did a concentration in Thermo-Fluids and to me it was more interesting than design, but then again I love aerodynamics
Just gotta know what you find appealing and you’ll be fine
😀
Intresting*complex
For some reason I read this in a very sarcastic voice and was very confused 🤣
I don't know how youtube recommended me this video but it really helped me understand that topic in triple point of water of class 11 physics.
I've seen P-T graphs before but never wondered what would happen at the triple point. This video is amazing!
Kind of satisfying when I saw the water turning ice when placed in sulphuric acid in from of a rectangle..
Perfect post for sub reddit oddly satisfying 😁

SAME LMAO
3:10 for those who can't wait.
Well😅 that was 5 second ago 🔥😂
You are sitting in a boat floating in the harbor. It is foggy and an iceberg floats by. (the triple point).
fog is liquid water droplets so small they don't fall in air.

@@jamesmcginn6291 actually, there is gaseous H2O in the atmosphere. The reason why this situation is different from the triple point condition is that the phases are not in equilibrium (in the triple point they have to)
@@chuviemilope
There is zero gaseous H2O in earth's atmosphere. Don't believe the myth. Don't take meteorology's word on it. They lie just like climate scientists. H2O conforms to phases indicated in the H2O phase diagram.
I only read about triple point of water in theory that was in my syllabus. But today I saw it practically and this enhanced my concept. Thank you. please prepare more of such concepts. Best of luck...!!!!
Mind blowing! Its so simple and clear! Thank you!!
Simple, clear and wrong.
H2o is still liquid at temps/pressures of atmosphere.
Thank you for a such a lucid explanation on triple point
Thank you for this explanation! I just saw the triple point of water being shown as a curiosity in another video and had never heard of it before.
I don't remember being taught this at school at all 😂
because it's not taught in school but in universities.
@@toanhien494 yes it is thought at my school atleast
Please remember that water in gas phase is invisible to the naked eye. Clouds that you see in the sky is not water in gas phase, it is condensated water (on small particles). The same with vapour/steam you see above boiling water.
I didn’t know that. Thanks for informing!
it's 3 in the morning, why am I here?
you are in zee indernet, vatching ein fiteo from a German in ein laporatory.
To see something amazing.
It's 3am for me too...
AHHH ITS ALMOST 5 IN THE MORNING FOR ME ;-;
Feed Me
Great content! I subscribed 👌 💯
Although i stumbled upon this Video randomly, i really enjoyed it. Very informative! Thanks :)
Idky this was in my recommendations, but this was amazing!
It's a legendary presentation.
In purpose I clicked the video and expected that it contains only explanations... practical is awesome which has proven something I thought not possible
I had worked so long in the thermal energy sector but had never seen the triple point. Thanks a lot for this experiment.
i liked learning about thermodynamics a lot so seeing this/having a proper, visual demonstration for the triple point is really cool!
Such a 'sublime' presentation! 😜😜
I always found this expriment kind of abusively presented : The frozen parts are frozen, not liquid neither gas.
The melting parts are liquid, not solid neither gas.
And same about gas "parts".
Yes you can see the 3 states of the same "material", in the same "local aera", and they all change quickly, but if each "portion" goes through the 3 phases, no one is really in the 3 phases at the same time.
Same thought
I am astonished! It's so amazing to see such phenomenon!
Thanks for your efforts
This is exactly what I want from a creator. No bullshit all content. Concise. Precise.
This was wonderful. Keep up with these super cool, highly educational experiments.
The Physical Cosmos exists in gray boundaries: one state of matter transcends into another, definite states exist, but finite states do not. Under the right conditions a vapor can flow like a liquid. So can fine particle of solid matter. Helium 2 is a mono-atomic powder with no viscosity, that is why it is called a super-fluid.
It was fascinating not sir could of u learn to smile
Imagine ourself there at triple point 😂😂
My teacher told me it was impossible. "as long as one piece of ice, doesnt matter how big, it will not start to liquify until all of the ice goes up to the melting point. Same with all materials." Tried telling him it is not so. Almost failed chemistry because of that argument with him. Imagine a long rod, ONE PIECE of iron.. maybe 20 meters or so. I can promise you, if you put one end into something that is really hot, hot enough for the iron to start to melt quickly.. the other end will not be as hot.
Ya I still remember that shit from school, obey the teacher is the real way of things.
God that sounds like an awfully unqualified chemistry teacher. Show them this video lol.
you kind of missed the point there. In normal conditions (1 atm pressure), ice in water will tend to cool the water in it to zero until all the ice melts. Only then will water start to heat up.
Your teacher is right. The water is NOT becoming gaseous It is evaporating. Evaporation involves microdroplets of LIQUID H2O.
@@AP0PT0SIS LOL. His teacher is right. Consult the H2O phase diagram.
my brain: "touch it!"
me: "why?"
my brain: "JUST! DO! IT!"
Really? No one? I have to be the one? Fine.
*OH BABY A TRIPLE!!!*
Imagine a solid, liquid and a gas-all existing at the same time. Sounds impossible, doesn’t it?
Ahem. Cats.
You taught this topic clearly... 😊 lots of love from Nepal ❤️
I can feel a burning passion in this man. Damn he REALLY likes making videos
I just love thermodynamics...
Your videos. Need to translate. Arabic
Thanks
Cheers mate, have a great 2019 all. Be kind to each other..
I read this in my 11 standard textbook and thought that it was a misprint hust very recently I came to know about but no one could explain this concept to me thank you after 3 years I finally understand it
And three years after you i could finally understand it!
I didn't even know that such a thing as the triple point existed. I learned so much. :) Thanks.

"Water will exist as BOTH water, ice ,gas"
He should have said water will exist as troth water,ice and gas.
This was an excellent video.
I don't know why I've never heard mention of the influence of pressure on the triple point of water from any other laymen's source. I've always been confused by the notion of some special temperature putting water in all three states because we never witness it. Now it makes perfect sense to me. There are two variables to consider and it is not all that mysterious though it is still interesting.
Anyway great video. Clean, to the point and scientific. Instantly subscribed.
4:30 rectangular ice crystal
very clear and very interesting, thank you
Thank you. What is application of triple point?
Can you please explain why snow flakes form dendritic structures.
And are there any instances where the principle is applied in organic chemistry to do a thing?
The three phases are (by definition) in thermodynamic equilibrium at the Triple Point (there is only one temperature inside the vacuum chamber) however else they may vary.
Excellent video please make such a video and make up educate
Clean, Crystal clear and No Bullshit. Perfect video
Can you tell me What pressure sensor type you used in this video ?
Those ice crystals were beautiful
Hopefully someone can help me. In recent years I have seen the value of absolute zero represented Occassion as - 273.16 but most textbooks say - 273.15. Even IUPAC has listed both temperatures in recent years. Today (14th Oct 2019) it has -273.16 but I have noticed they have listed both temperatures on that reference site. (no kidding it seems to change on IUPAC) Has there been an official definition change in the past 5 or so years or are these typos?
The ratio of views to this channel’s subs is everything wrong with TH-cam right now…….
this is so cool i’ve never heard of a triple point before
Woah diggah, habt ihr das in Google Übersetzer gehauen!?
Some people are impatient as hell, goddamn
Just saying, but Clouds are not gas. They are tiny water droplets crowded together. Other than that, good video! Keep it up! :)
So if you fly there taking vessel you can collect water ??
@@dhocris7studio technically yes
Is there a simple web page with all all or most phase diagrams?
After water and carbon dioxide, they are really difficult to fined.
Thank you soo much sir ☺️✨
In Indian Religious texts, Triple point of water was given 5000 years ago. We don't need modern science to prove it.
Lmao
@@iresineherb7To be true, that's what 80% of Indian population thinks, even in Indian History Textbook it is written, not only this they have written that Pythagoras theorem, Maxwell law, Electrical bulb, Aeroplane, Differential equation, Algebra, Geometry, Trigonometry, law of Relativity and all other things were discovered by Indians 1000`s of years ago. I am not lying you can search it on internet there are many articles on it and Indian government supports and it is written in our History Books that are published by the Government of India. These NCERT books are also available in PDF format you can read it.
It was a great!!! video
Keep it up dude 👍
Ok, now say:
"I'll be back..."
"uzi nine millimeter"
"Get to the chopper"
"Asta la vista baby"
Nice, I just want to know that if the pressure is kept below triple point pressure that is 611.5pa and if we increase the temperature does the water directly goes to vapour state? I just want to see that. If possible kindly show that also sir.
Extremely difficult to see sublimation with invisible gases, you would really only see the ice getting smaller.
You can get the same effect with dry ice, but with dry ice it is cold enough to create a cloud like effect.
@@MsSomeonenew
Sublimation produce vapor. Not gas.
@@jamesmcginn6291 no sir sublimation produces gas
@@jeevansamrudh5600
Sorry, but that is impossible. The myth you are falling for is this myth that clear, moist air can only contain gaseous H2O because otherwise we would see it. This is mistaken. As an implication of its high surface tension, H2O produces very small nanodroplets of LIQUID H2O. There is no gaseous H2O in earth's atmosphere. You are a victim of a very popular group delusion:
We all grow up believing that the moisture in clear air is gaseous

This is not even remotely possible.
Outstanding and crystal clear explanation! Thanks a lot!
Good one
Of all the elements in periodic table iodine is the most weird of all. It can go to sublimation and it can also undergo to the triple point at the same time. If you heat it above its melting but below its boiling point you'll make a liquid iodine....
Question : If we touch it...will it be hot or cold?
the temperature is practically 0 Celsius so it is cold
do not confuse boiling the process from liquid to gas
boiling does not mean hot
look mercury it is metal and it is liguid
if you touch it will be hot?? as any other melted metal??
ANIKHTOS okk got it. Thank you :)
You can also experience cold burning.. like liquid nitrogen poured on hand.
@@sonaruo i touched boiling tungsten and it was hot
@@Blox117 tungsten's temperature will be high since u provide heat, whereas here we r reducing its internal energy by reducing the temperature and pressure , we feel it cold as temperature is independent of the state in which matter is present
That background music starting at 3:23 is soooo spooky. Made me slightly unease and caught me off guard and I'm not the one to easily spook lol. It's like ghosts singing some sad song
Awesome video. You made it perfect. Congrats and Thanks :)
When you realize how much of a car enthusiast you are when recognize just the T tops of the photo examples happen to be the same as your car. How random af. 😂😂😂 I love my Z32 300zx
Super explanation sir
I didn't see this type explanation sir.
We are lucky to have you as a TH-cam teacher sir❤❤❤❤❤❤😊😊😊
I don't why I don't understand this P-T diagram even in my college. Can any one provide me with some good stuff explaining this diagram?
Hi, Dear : Well done & wonderful. Highly appreciable & thanks.
❤️❤️❤️❤️❤️❤️❤️😍
hello sa mga beda jan
Rather than co-existing in all three phases at once, isn't the water really showing all 3 phrases within the same chamber because conditions were right near the triple point and any VERY SLIGHT variation in temperature or pressure in any one position within the petri dish resulted in the water either freezing, boiling or remaining liquid? What would it look like if you could somehow keep conditions in there absolutely perfect?
If you could keep conditions exactly at the triple point, you should see liquid water and ice, and bubbles where the liquid is boiling. It would be an equilibrium where evaporation, condensation, freezing and melting were occurring at the same rate. Any slight perturbation in conditions away from the triple point will result in a shift towards water, ice or boiling.
nice to see that
I can make all 3 states of H2O much easier! Put an ice cube on a hot frying pan...ice, water, and steam all together at the same time:)
The idea here is awesome, but I’m actually disappointed, cause it ends up not being any more impressive than my way above. I thought it was going to be a single mass of all 3 phases mixed, somehow. Like an ice cube that was ALSO liquid and vapor, not just ice WITH water and vapor. Still pretty cool, tho.
you have a heavy german accent and use a bunch of terminology that is easy for students to understand, but not for laymen. From evacuation to saturation pressure to nucleation sites. otherwise great video
That was one good explanation of the topic. My sincere gratitude.
Thank alot
“Any pure substance can exist in 3 phases.”
Does this include helium?
I was expecting some sort of funky material not different parts in solids, liquids and gas.
Thanks sir
My siblings will have their minds blown when they hear that you can boil water by freezing it (hyperbolically speaking) cheers
Thanks ...expensive apparatus .?.can we use those on variety of material amazing works...thanks
Amazing!!

Why there is a P-T diagram only for water but not for almost every other compound? It's super hard to find such diagrams for e.g. methanol, DCM etc. etc. etc.
Our physics teacher is handicapped and thus he doesn't moves much during his classes, just sitting and explaining from the book verbally. The classes aren't that exciting, but what's his fault after all...
Pretty awesome but how can this be applied to construction, manufacturing, medical equipment, etc.???
ik what tripple point is, ik thermo but watching it to force myself to watch such stuff. and this boi worked on audio setup really vell so yeh
Could you please tell me how long it takes to run the experiment. I m a phy teacher in UK, thanks. I want to demonstrate this for my A level students please.
Why did you use marbles?
Did you use tab water or distilled water?
Many many thanks.
No body ever mention that at the triple point, goofy music might start to play in the background! This a huge discovery... I wonder if all 3 phases form a band and start playing? Lol
Easy way to see triple point for water: heat an empty frying pan then toss an ice cube in it...
BOOM! Solid, Liquid and Vapor
But can 1 molecule by itself reach the triple point? Having a many molecules will most likely always give different viewing aspects. Like this triple here. Or am I missing something?
Wow I never knew the triple point of water causes German EDM techno music. Even more astounding when putting sulphuric acid in the chamber it causes faster German techno music.😁
Hey !! I have a doubt please can you clarify.
At 1:33 you said that the pressure should be 6115 pa ( according to triple point of water )
But at 3:03 you took the pressure around 1.19k pa. Whyy ??
He said his machine can't measure pressure that low..
Chem engg double graduate but seeing triple point actually for the first time. Now I can die happily...lol...
🕵️♀️CAN U TALK ABOUT NEGATIVE PRESSURE IN OUR ATMOSPHERE AND SINK HOLES?..
It is NOT boiling.. Maybe it.s the oxigen particles who came out in low presure(vid)
