Here is an example of true, internalized knowledge: While explaining how ice functions on a lake 9:10 , Chuck mentions that's a bear's dream (fish being pushed to the surface from the bottom up), and Neil, without batting a lash responds that the bears hibernate and would miss this effect. LOVE IT!
@BS - 10GM 720145 Turner Fenton SS no, unfortunately not. Do you slip on ice with your shoes? The surface area of your soles is much bigger than skate blades... How much pressure do you exert under your soles? Not enough to liquify ice, but you slip on ice..
... sentience = having sensory experience... he already has sentience. Besides your faulty firm of respiration causing cognitive impairment; why do you mouth-breathers continue to misuse the word "sentient" where *sapient* belongs?
Sometimes I’d see your video title and think “oh I already know why” and then I’d watch the video and somehow I’d still end up learning something that I didn’t know before. Love your content!
Even though I knew why does an ice float (which is in the title of the video), I watched it because Neil always provides some more interesting information)
Neil, buddy, yes, ice expands with great force, but what Actually causes a lose to burst, or more often, a fitting, is the fact that water cannot be compressed. When you plug one end of a pipe (the shut off on your sink), it blocks the water from displacing the ice and the pressure formed therein will burst a fitting. Also, since the early '90's PEX is standard supply lines for all commercial and residential. Is incredible plastic. Check it out. Its in Your house... Love you man. Thanks for everything.
Water expands in a solid date due to it's molecular shape and the configurations multiple molecules are forced to create thereof as the molecular movement slows and becomes a larger structure due to the polarity of the molecule. But it's always fun to see NDT put such stuff in terms we all understand :)
I feel chuck is missing the face to face aspect. He used to be more genuinely excited about the science behind simple things. Hope to see you guys together again in the same room soon!
Another way the force of freezing water helps life; it breaks down mountains into dirt. Water in cracks freezes, fracturing the stone. More cracks and freezes, more gravel that tumbles down the river to become soil. Erosion would take so much longer if not for 'frost heave'.
Hi ! StarTalk, I fan here from México, I had certain knowledge about those features about ice but why is it like that ? I mean is there another compound that behaves like it ? Or is it unic to water.
When water freezes, intermolecular bonding causes the molecules to arrange themselves in a structure less dense than if the molecules were freely moving.
we used to have milk delivered to our doorstep in bottles when I was a kid , in the winter the milk would freeze and expand .... and push the foil top off .
Anyone who lives in a northern climate like I do in canada, knows that snow and ice will protect your lawn underneath during the winter months. It not only protects from the harshness of the weather but also provides a temperature comfort zone. And you know this is true because the one winter where you do not have snow or ice, your lawn is very noticeably less healthy...
Absolutely true, in my city, Fresno Calif, the Alaska Express visited our city in the 80s, I went to work, I was a Fire Captain at that time, as the temperature Rose Our entire Department went from building to building shutting off the sprinkler valves because of broken pipes, our water system was under extreme stress my crew was in the down town area and water was running down every street, in most cases we followed the flow to find the broken pipes, breaking into buildings to get to the plumbing, and then leaving the building open and going to the next break. Fortunately that only happened once in my 27 years as a firefighter
Wow, that's why the Zamboni leaves the rink wet and slick. It's just crushing the top layer of ice at a set temperature, warming it enough to become smooth!
This topic was discussed in one of the Cosmic Queries videos, and I was actually looking for that, but couldn't find. It's cool that they made an explainer video out of it. Also, if someone remembers what Cosmic Queries video this topic was in, please give me a link or title of that video.
This question is off topic but your video about your master class inspired me to ask it. In your ad video you discuss about knowing enough to know where you can be wrong. So it made me think of a question for you. When it comes to the expansion of the Universe how do he know it is "Expanding" vs our Universe "Unwinding" ? It may seem we are expanding but we are in perception of the Universe time dilated vs. what came before the big bang.
@dave randell the idea came to me in realizing that even though some thing physical is made of many things it doesn't mean that physical nature is an illusion. Indeed it could mean that space itself IS the physical object. Ty for the reference.
I'm still not sure I understand WHY water has a higher volume when in solid (ice) form. How is it that other molecules get closer together when they become solid? Solid vs liquid metal for example. Is water the only exception to the rule?
Missed opportunity for an astro physisis :P I thought Neil would have mentioned the other moons and planets with Ice covering the surface and seas underneath while talking about our own planet and seas. It was the perfect time to talk about how life could be under all of that ice.
The ice ball press unfortunately is just melting the ice from the conductive property of the metal which transfer heat into the ice, melting it. It doesn't work as well once the press becomes cold. So it's not the pressure that melts it. The pressure is from the weight of the press which is very small and the surface area are as big as the ice. So there isn't as much pressure than just heat transfer.
The skates melting ice to make it slippery is kind of a misconception, tho that does accour in some small way its usually not thought that this process makes ice slippery and allow skates to glide across it. Someone in flat shoes will experience the same lack of friction or slippery-ness, they will be dispersing thier weight over a much much greater area decreasing the pressure the ice is under. Even holding ice in your hand in 1 atmosphere/14.7psi ice is still slippery to the touch. Scientists are not 100% agreed on what makes ice slippery. I till love you guys neil is prob my favourite science communicator. Love the videos keeps me sane during lockdown.
I thought the glaciers on water melting made the levels rise because they are made out of fresh water, and the ocean is salt water, so they are pushed higher above sea level. Is this cancelled out by the fact that after they melt, the fresh water spills into the ocean and mixes with the higher density salt water?
I don't know for certain, but I suspect that copper is used to make the ice spheres due to two properties of copper. The first, and one I suspect is probably more likely, is that copper has one of the highest thermal conductivities of metals, the other is its anti-microbial properties. I believe copper is beaten out by silver in thermal conductivity, but silver costs more.
Great video as always! On the same topic, does anybody know exactly how do "ice tsunamis"/ice shoves form? I'm very curious about this one and there isn't a lot of info about them on the internet
Yeah but if the ice melts off the land, then the land rebounds and gets higher. 3.98 degrees celsius is when water is most dense. Oh and I have skated at -20 and it is not as “slippery” as ice near freezing. At even lower temperatures cross country skis dont glide as well. Driving on -40 is slippery yes but not as slippery as driving on -5 ice. Life in Canada has proven that. So while the science of ice skating is not known perfectly it does require some melting of the top layer to create the slipperiness.
Once again I will guess before I watch the video. As water freezes it expands which increases the surface area while the mass remains a constant. Once it's frozen ice has less mass over a greater surface area which causes it to have less gravitational pull per unit square than water. Now I will watch your video.🍺
Can we take a moment and appreciate how social intelligent Chuck is? And how his mind works at astonishing speed. The way he adapts to what Neil says, with humility and witt, is beyond me. If Neil is a rockstar of science, Chuck is a rockstar of social intelligence.
I clicked on this video because I wanted to know why ice floats. I was already aware that water has maximum density around 4 degrees C and that ice is approximately 9% less dense than that, and hence it floats, but that doesn’t help with why that is the case. What I wanted to understand is what is unique about water that causes it to exhibit this particular property. I did a bit of research and learned that: “Water is the only non-metallic substance that expands when it freezes.” So, that suggests that this property is an unusual one which further drives my curiosity as to why it is so. Any materials experts out there who looked into this a bit deeper that can explain why this is so? Thank you.
Well, if we are to get very real here, you never actually physically touch anything. While the explanation is simplified and entertaining, the science is 100% accurate. ua-cam.com/video/yE8rkG9Dw4s/v-deo.html
They compress the ice into slabs, and then the bartender cuts a square off, and chips away at it with a fork whilst rotating it in his hand to give it a spherical crystal golf ball affect.

LOVE IT!
I actually thought at first they are talking about Bear Grylls
That also means ice skating wouldn’t be invented as fast
Neil is amazing because of stuff like this. True!
When he said this I wondered about Polar bears ...
I suppose there wouldn't really be a need for them to hybernate anymore if this were true, huh?
Neil is an educator indeed. He's explained this amongst other concepts over and over again in several videos. Yet he still shows such enthusiasm!
But his explanation why we slip on ice is wrong... Unfortunately
I know! I can't imagine being a teacher/educator and teaching the same stuff every year with a similar enthusiasm
@BS - 10GM 720145 Turner Fenton SS no, unfortunately not. Do you slip on ice with your shoes? The surface area of your soles is much bigger than skate blades... How much pressure do you exert under your soles? Not enough to liquify ice, but you slip on ice..

No mouth-breather is human, they are merely intellectual.

Chuck looking for his glass of water. He looks so excited :D. Great video guys!
Whenever I get out of cold water now I'm not saying I've shrunk I'm saying I got more dense.
Hey, what happen to that bumpin intro? I enjoyed listening to the bass at the end of the intro, what happen, man
It was getting old, tbh.

I mean is there another compound that behaves like it ? Or is it unic to water.
When water freezes, intermolecular bonding causes the molecules to arrange themselves in a structure less dense than if the molecules were freely moving.
Wasn't it 4° C when water was densest?
Yes, it's 3.9something, so very close to 4 if we round up.
I didn't know I needed to know more about water until now

So, an ice ball press doesn't work by pressure, sadly, it works but rapidly conducting ambient heat into the ice slug and thus melting it super fast.

Intro is awesome 🔥
That bar turning into a ball of ice is interesting . Making perfect balls all the time or almost...
Thanks again Neil and Chuck awesome
The look on neils face when Chuck has to get a glass of water is priceless.
I have ice ball molds love them
I'm curious about temperatures at the bottom of the ocean and if they are below freezing and what are the physics occurring if so.
Ouuu that new intro doe!!
Chuck is the best!
Love the new intro
Chuck gets excited and Neil shuts it down way too often. Neil can be entertaining at the cost of other people engaging.
I got Neil deGrasse Tyson's masterclass ad on this video.

hey Neil! you, Chuck, & the ice are my. ASMR for the evening! 🥰
That broken pipes bit was stressful
I remember this grin high school chemistry.
Do any other known liquids have this property? Thinking about exoplanets and possibilities for life...
surprised that they didn't mention that you can freeze water at room temperature if you put it under vacuum.
I LOVE CHUCK! And you too Neil 🌟
I'm sure someone is going to use that clip of Neil about ice caps melting not rising the sea level in an argument against climate change
I love that poster and also the logo. Where can I download an HD version of this?
5:05 What will produce a rise of that magnitude in sea level? Where does Chuck get this data from?
4:45 Even melting of all ice thats already on water is a matter to worry
I though 4 deg C is when the water is at its densest (that's what I learnt in my high school), but Dr. Tyson says its 3 deg C 🤔
Are there other compounds (or elements) that are less dense in a solid state?
Please make a video on snowflakes☃️🌨
I like today's episode, its pretty Cool.
What about ice XI? Do you think that forms in space?
I'm still not sure I understand WHY water has a higher volume when in solid (ice) form. How is it that other molecules get closer together when they become solid? Solid vs liquid metal for example. Is water the only exception to the rule?

10% up 90% down? I'm going to go see this right now!
I wish he'd go into how the crystalline structure of water turning to ice comes about. That's what actually makes the volume increase
I want a video whereby Chuck brings Neil to the bar

Water is its densest at 4°C, not 3°C
That's an ice cuboid (not cube), Dr. Tyson😜 I'm a big fan, maybe like everybody else!
I have a question
Why do dead bodies (humans and animals) flat?
Are flesh, bone and fluid less dense than water?
simply thanks gents!
But why does water expand when it freezes? What's different about h2o from nearly every other material?
We need a hangover movie with Chuck ndt and Bill nye trying to find Joe Rogan after a night of carnage
Why is that Church always gives the perfect reactions to Neil's explanations of physics phenomena?
I always believed that ice floatation had to do with the tiny air bubbles being trapped within the frozen ice...
If all the fish goes down to the bottom in the winter. Does that mean it is easier to catch fish in the winter?
The bar trick that Chuck describes happens due to Sublimation of ice.
Can we take a moment and appreciate how social intelligent Chuck is? And how his mind works at astonishing speed. The way he adapts to what Neil says, with humility and witt, is beyond me.
If Neil is a rockstar of science, Chuck is a rockstar of social intelligence.
