Thermodynamics - Explaining the Triple Point
HTML-код
- Опубликовано: 1 окт 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.
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 😁
I've seen P-T graphs before but never wondered what would happen at the triple point. This video is amazing!
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.

SAME LMAO
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...!!!!
3:10 for those who can't wait.
Well😅 that was 5 second ago 🔥😂
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!
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
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
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!
Although i stumbled upon this Video randomly, i really enjoyed it. Very informative! Thanks :)
Idky this was in my recommendations, but this was amazing!
Such a 'sublime' presentation! 😜😜
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.
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
Great content! I subscribed 👌 💯
This was wonderful. Keep up with these super cool, highly educational experiments.
This is exactly what I want from a creator. No bullshit all content. Concise. Precise.
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!
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.
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.

"Water will exist as BOTH water, ice ,gas"
He should have said water will exist as troth water,ice and gas.
It was fascinating not sir could of u learn to smile
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
Cheers mate, have a great 2019 all. Be kind to each other..
Excellent video please make such a video and make up educate
I didn't even know that such a thing as the triple point existed. I learned so much. :) Thanks.
Imagine ourself there at triple point 😂😂
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.
Ok, now say:
"I'll be back..."
"uzi nine millimeter"
"Get to the chopper"
"Asta la vista baby"
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?
Imagine a solid, liquid and a gas-all existing at the same time. Sounds impossible, doesn’t it?
Ahem. Cats.
I just love thermodynamics...
this is so cool i’ve never heard of a triple point before
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!!!*
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....
4:30 rectangular ice crystal
Is there a simple web page with all all or most phase diagrams?
After water and carbon dioxide, they are really difficult to fined.
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
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

Your videos. Need to translate. Arabic
Thanks
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?
Clean, Crystal clear and No Bullshit. Perfect video
very clear and very interesting, thank you
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.
Those ice crystals were beautiful
Hi, Dear : Well done & wonderful. Highly appreciable & thanks.
Can you tell me What pressure sensor type you used in this video ?
The ratio of views to this channel’s subs is everything wrong with RUclips right now…….
It was a great!!! video
Keep it up dude 👍
Awesome video. You made it perfect. Congrats and Thanks :)
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.
I was expecting some sort of funky material not different parts in solids, liquids and gas.
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..
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
Some people are impatient as hell, goddamn
“Any pure substance can exist in 3 phases.”
Does this include helium?
the temperature reduced to below zero just by evacuating the jar this is how laws of thermodynamics works
Outstanding and crystal clear explanation! Thanks a lot!
Good one
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.
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
Woah diggah, habt ihr das in Google Übersetzer gehauen!?
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
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?
Thank you for great demonstration...... I wonder everytime when my lecturer explains triple point....now its cleared.👌👍👍
Thank you soo much sir ☺️✨
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
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.
Divine Fingerprint On Creation. “Let Us make man in Our image” (Genesis 1:26)
Cool, but the last time I checked, there’re more than three phases. Keep adding pressure and things get weird.
Thank you, i've never heard of this before !!!
You left out something that you touched on. ..microscopic thermodynamics of dilute gas systems involves the "deminson " time. It does not exist at triple point. Explaining this gets complicated until and unless you deal with quantum physics as with all divisions and disagreements, and state your laws of either creationism or whatever you feel is your level of enlightenment and understanding. Is time relevant to what you believe. If yes, then , adaptation of "physical " properties can be more clearly understood. Everything moves in one direction, not physically, but in the motion of the understanding of time. Uranium is lead, it just hasn't arrived there, yet. So then comes the understanding of our Creator's secrets. The objective observation of your point of referenced to time. The sun is helium, we are witnessing it as time.
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.
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...
Non-physicist/non-chemist speaking: correct me if I'm wrong, but isn't it true that the triple point is a purely theoretical concept? Nothing really exists at that temperature and pressure STABLY, as the pressure and temperature point of the triple point is just that, a point, i.e. an infinitely precise point of the intersection of the requirements of three differentiated states of matter. Temperature and pressure in any real context, surely, are continuously fluctuating, given that they are measured on a precise enough scale that one notices the change. Hence the triple point, in practice, is not a stable, perfect equilibrium, but rather a close approximation to that, where the temperature and pressure are in fact fluctuating chaotically around that point, creating each phase of matter some of the time, but never actually having a given part of the matter exist in all three phases at once, at least not stably for long enough that one can capture and see it.
very nice bro I'm ASLO student of mechanical engineering 4th year .
love from INDIA bro
Great video! I had never such an experiment, only studied about it (I'm currently finishing my geology degree) , but as it's commonly said, an image is worth a thousand words. I have a question, though. In a moment when you repeat the experiment with the sulfuric acid inside the chamber is possible to see how water crystallizes in a rectangle-like shape, but I know that water crystallizes in the hexagonal system. Does that happen because of the velocity of the crystallization process under those circumstances or does it have something to do with the H2SO4 you added? I'm asking because logic and experience tell me that if it happened because of the fast crystallization, the film formed would be more or less shapeless, but I'd never have thought it to be formed in rectangular shapes. Can you change so easily the crystallographic system in which a mineral forms by changing such parameters (i.e., pressure and temperature) or is a matter of 'catalyser' addition (to name it somehow) ?
Thank you for your time, keep up the great work!
So this is neat and all, but what practical applications in the world real can we apply this knowledge to?
Triple existence of phases in equilibrium appears as a point in P-T diagram but actually is a line in P-V-T diagrams making to say that triple point can occur at different points i.e., at different specific volume compositions then why it is always referred to as a point.help me.
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
Super explanation sir
I didn't see this type explanation sir.
We are lucky to have you as a RUclips teacher sir❤❤❤❤❤❤😊😊😊
This is fantastic stuff. It doesn't make me cringe like lots of other WOW SCIENCE!! hype channels. I can watch it without wanting to kill myself.
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?
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.
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.😁
But why would you say the water is in a state of solid, gas and liquid when some of the water is frozen but the other part is boiling. Its not the same parts, but a change.
I see it like an ice cube melting then reforming into frozen water once the temperature drops. Now do that extremly fast and it looks like water is both solid and liquid but in truth it is just changing form really fast and not both at the same time
Maybe, this is what the god of Christianity was trying to teach them with the Holy Trinity, but the founding fathers of Christianity completely misunderstood it for a supernatural concept that makes zero sense.
