The coldest materials in the world aren’t in Antarctica or at the top of Mount Everest. They’re in physics labs: clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low give scientists a window into the inner workings of matter, and allow engineers to build incredibly sensitive instruments that tell us more about the universe.

1 question
Is it true that the cube of ice is hotter than a cup of hot coffee . If yes then why is it so?
there is no Arabic language in translate and most arab people watch this channel please solve this problem
Hey TED-Ed, I have a question. How do we calculate how much times something is colder than another thing? Is it just linear, based on kelvins, or is it calculated based on the energy?
I thought that the coldest thing in the world was her heart :(
okay Ted now riddle: today is 0 celsius and tommorow will be 2 times colder, what temperature will be tomorrow?
The opposite side of my pillow.
Lol I flip my pillow to the cold side because I like it when my pillow is cold
LMAO
Agreed.
Heh, nice one
Yessss
The coldest thing is a toilet seat in mid winter season.

I misread it as "What is the coolest thing in the world?".
Julian the Ivysaur Lol 😹
Lol same
Lol even i love pokemon
Well, isn't it cool anyways, it's already cool in one sense.
Me too
i think there is nothing more colder than -273.15c which is the 0 kelvin, the absolute limit of cold temperature, where matter has no kinetic energy. is there anything much more colder than fully paralyzed atoms?
it is impossible to reach 0K.
BUT, there are definitions of temperature which are based on the occupied energy states within a group of particles which allow negative temperatures. (for positive temperatures, the definition is identical in its interpretation for the real world) and we have reached negative temperatures.
(technically, those 'negative temperatures' are hotter than any possible positive temperature.
in other words: if you bring two bodies of different temperatures into contact, energy will flow from the hotter to the colder one. if you bring atoms with negative temperature in contact with atoms with positive temperature, the energy will flow from the negative temperature to the positive temperature one in every case!)
Her messages, her heart, her soul
Haha lol the animation when she said there’s a limit to cooling down LOL. Glorious. LIKE
these videos are so satisfying and helpful as well
Teacher: List the states of matter in descending order of temperature.
Normal kid: Gas, liquid, solid.
Nerd: Plasma, gas, liquid, solid.
College professor: Plasma, gas, liquid, solid, Bose-Einstein condensate.
Students: What the heck are you doing here?
Hooo.... Chilly out there!
What's the coldest thing in the world?
Todoroki: My soul
My heart, soul and emotions are much, much colder...
I've always wondered why humans sweat when they're hot, but objects sweat when they're cold
humans sweat to regulate body temperature.. Releasing sweat cools down your body...
Objects don't "sweat" when they're cold.. If sth is very cold, and you keep it in open air, it will transform nearby gaseous water molecules in air to liquid... It's known as condensation.
The coldest thing in the universe...
My heart...
for those of you who don't know, average kinetic energy of a particle is measured in degrees celsius or kelvin, that's why she said that we percieve movement of particles as heat ...
My heart. My heart is the coldest thing - Snow Queen.
U wanna know the coldest thing in the world?
*My soul :)*
Cool answer
The metal slide in the shade
Cold. Been excommunicated cause I’m cold. My temperature’s been rated and I’m cold. Bring to me my big old sweater, nothing more will make me better.
Scientists: Magneto - optical trap
Me: *Freeze Ray*

This is how “time travel” will be possible. Feel me?
So cool ♥
What is the coldest thing in the world
Me:My Crush?
Science:No its-.. • , •
it is amazing
*WHAT'S THE COLDEST THING IN THE WORLD*
Me: *HER*
That’s almost as cold as my foot when I step in an ice puddle with socks on
the coldest thing in existence?
her attitude
:(
Who's attitude?
my heart...
What's the coldest thing in the universe?
Probably my ex wife's privet parts
Got it!
How do they measure such a low temperature?
Her heart...
What‘s cooler than being cool
Clouds of gasses ALRIGHT ALRIGHT ALRIGHT ALRIGHT ALRIGHT ALRIGHT
Freeze brain "am i a joke to you"
So can we make a freeze Ray now?
I wonder how they even measure coldness at that scale.
Basically a freeze ray
Haha, its my heart.
the coldest thing in the earth is her heart.
My heart
I thought they were going to say my soul
Me and my crush's conversation is the coldest
395 000 000 times colder than my fridge? How is that even possible if the absolute zero is 0 Kelvin or -273,15 Degrees Celsius? Where do you get those numbers from?
في كتير ناس عربيين بتابعوكن ياريت تترجمو رجاءا
Wow you doin me a educate
*unorginal joke about their ex* 😂
Daoloth Ben swolo
I was expecting someone to say something like that
Oh good so I wasn't the only one thinking that
lmao 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Lmao clicked just read ex jokes
Nobody:
Weatherman: today, the atoms are moving very fast
up in the north you can see they are moving a bit slower...
I will be honest with you.
That afforded me a pretty good laugh.
PaperTonne 해료
In this cluster of atoms, you should be covered in a thick layer of atoms that don’t like transferring motion to other atoms so that your atoms don’t move slower.
Then fix the atmosphere already
The coldest thing on Earth is me when I am without my blanket
Check My Playlist aaaand I see you twice O.o
Check My Playlist can't be you only -_-
Check My Playlist. I take my blanket even when it's hot at night
Aliyah Happy tell lies and get likes. Nice way
Check My Playlist I checked your playlist it's so cool

@A E exactly 💯
Yes and yes definitely
@A E what?
The thing doctor put in my mouth is very hot and stiff
*WHERE'S MY SUPER SUIT*
WHY DO YOU NEED TO KNOW?!
THE CITY IS IN DANGER!!
MY EVENING IS IN DANGER!
SERIOuSLY HONEY. wHERE. iS, MY. SUPERSUIT?
LoL
(joke) One scientist was cooled down to the absolute 0. But he was still 0K...
would've been better without "(joke)"
_j o k e_
(joke)
Nice
(Old joke)
When you scroll below this comment, keep in mind that there will be thousands of 'my ex's heart' comments.
Thanks for the warning. Gonna stop right here.
OMG i recognise you from jacksuckatlife
What is the coldest thing in the world.
Me : Hey wanna hang out ?
Crush : *seen*
I can feel this bro...!!!
Why did I come to the comments section expecting this to be the main joke in different variations.
The -1000 degree cold knife, obviously

Onyx VII7 thank you 😊😊
KittyCat Gamer right 😁😁
I was about to say that
Me: what's the coldest thing in the world?
Ted-ed: Good Question.
Watching Ted Ed while chilling in my living room
Cool
Idk what kind of chilling you mean.
Like relaxing in your room or literally cold in your room.
JAMSit JOLOXx lol
Ted ed and chill anyone? ??
Same
Me: *Walks over to freezer*
Also Me: *whispers* Tell me your secrets.
That's almost as cold as my soul
The 7 hearts make up for that.
So edgy its boring
That's dark
Was too distracted with the animation to listen attentively. 🙊
reading the captions while listening helps a lot! I cant pay attention otherwise lol
Dope animations!
Cool animations, more like. 😉
I think I learned more than half of one semester in our physical sciences subject in a 4 minute video 😃
Wow, it's amazing that even at that low temp, atoms can still move some cm/s!
If you think about their size, it is like a human being able to move at light speeds even in the "slower" state
do you mean their radiation waves per second added together?
no it's not lmao
Answer: people who move when their dog is sleeping on their bed
oh NOOOOOOOO
Ah, temperatures. Where the value of 0 depends on a fastfood chain: K F C
It's crazy how we can use really low temps to create scientific equipment. That's so beautiful ❤️
Welcome to science, that's not even the start of it...
and hot laser to get there.
I'd say that it is impressive how reducing particle movement makes a difference in so many experiments.
Coldest bobs
you say the exact same thin on every science video
My BRAIN : Most Negative thing in the Universe
My HEART : Coldest thing in the the Universe
My BODY : Most Useless thing in the Universe
This comment deserves to be on top.
I think you have self esteem issues :/
I believe the coldest thing is my passion for learning when I'm sitting at an extremely boring lecture at my university (as opposed to watching a TEDEd video when my passion fires up).
TED-Ed, your videos help me learn new things everyday in a way that I just keep waiting to watch newer TED-Ed videos.
Not to mention, the quality of animation has improved to such a point, it seems like you can make an animation movie out of this; seriously they are beautiful and just keeps getting better.
Hope this can sustain itself and spread knowledge throughout the world for the nest 100 years.

It’s based on the third law of Thermodynamics.
Really fascinating .
This reminds me of that iconic dialogue
"He likes it cold".

Help with the very coldest atoms in a...
I'm the only one who noticed that?
Maybe you are...
''...coldest atoms in it''
The Fulfilled Yeah, do you not understand what it means?
"what's the coldest thing in the world?"
Me: it's the human heart.
Room temperature
The coldest thing in the world is your soul when you go to college.
A Tax lawyer I can see that coming.
Relatable, I became an introvert after my 7th year in college for a doctorates
The coldest thing i ever held in my hand is
Ice
That's ice cold, man.
*oooo... Chilly*
The animation gives me soooo much inspiration and motivation to draw.
Can anyone explain how 0.10 ( for instance) is 395 million times colder than 278K ( normal refrigerator temp )
0:24
It's more like 0.0000007K
Meanwhile your science teacher:
"What's the thing that retains the least heat in the world?"
What does "times colder" mean?
Most probably the ratio between the temperatures (in Kelvin) of the objects under comparison. I.e. if one object is 45 degrees kelvin and another is 15, then the latter is 3 times colder.
And if something is like 10 degrees and something else is 0,001 degrees, thats 10k times colder.
Diogo Gonçalves So 10 degrees is 10k times cooler than .001 but only 10 times cooler than 1 degree? Doesn't make sense
This was the first question I had too. I have thought about this question before and the conclusion I came to is that the only way to compare temperatures like this is to compare the two systems average kinetic energies.
Crushnaut like the speed of the atoms, something like that?
This channel is very useful to improve our english skills and our knowledge.
Awesome video ted ed I learn so much every time I watch ur videos ❤️
I love this channel😘
I think animation is a little bit too much . This is not a lyric video. You don't need to "animated" every words/phrase the narrator said.
I want riddles the voice is relaxing
The south bend shovel slayer....
Coldest thing ever?
Me : MS DHONI
nice.
are they indirectly talking about bose einstein condensate?
"What is the coldest thing in the world"
me:hmmm my Brother's heart
My friends say that "my jokes are coldest"... Sometimes they also complement by saying "0k"
I feel really proud

Ali Hadi Babar bro, how much time did you spend just to scroll down to find a two year old comment that I even forgot about? Pathetic
Loved it! Thank you for this great video, keep it up :D
