What is Supercooled Water? How does it Work?

Here we demonstrate and understand supercooled water, which is water which has been cooled below the freezing point, yet remains a liquid. When supercooled water experiences a shock, it rapidly changes from liquid to solid.

I have worked in commercial refrigeration for about 35 years and have observed this phenomenon in ice machines. The circulating water can suddenly turn to slush everywhere in the water system all at once. I was measuring the temperature of the water in the trough of a machine one day and saw a low of 27F just before it all flashed to slush. More modern machines (built after about 2005) combat this and rarely do it, but the old ones would do it every time on the first batch.

Thank you explaining it so well !!!! ❤ Grateful.

[@joedasilva134]

Very interesting.
Loved it!

[@MathAndScience]

Glad you enjoyed it!

I prefer a supercooled beer. I will try it this weekend.

[@thesoaringdutchman]

Won’t work, the mix of alcohol and water already won’t work and the other ingredients make it impossible too

[@tr.buuvibrian8162]

Might block your gut😅

[@mathsprofabderrahim]

Fantastic 👍👍👍

[@MathAndScience]

Thank you! Cheers!

[@shrutishukla717]

👍👍best explanation

[@KisDraga]

i accidentally did this with a bottle of sparkling apple juice i put in the freezer. It didn't freeze down until i opened the bottle, then the bubbles triggered the nucleation. it was so cool!

[@clarckkent1880]

Hello Professor, will you consider adding salt to ice and the liquid ice water produced that is being prevented from reformation to ice due to that addition of the salt causing the alteration of the ice water molecular structure due to the salt , remaining as ice water with at very low temperature below feeezing also a form of liquid subcooling

[@ieeikanae]

Sometimes I put my bottle of cola in the normal freezer for around 2-3 hours and this happens, great taste too. Always thought "super cool!" Well so it's called supercooled fluid.
I have to be very careful when opening it as for a high possibility it bursts uncontrollably as if it was shaken real hard before putting in. Why exactly is it?

[@richasinh]

😂

[@M5TABBYCAT]

Ahhh. Thank you.
But when you moved the water bottle slightly how come it didn't solidify?

[@fahimkhalasi4115]

sir can you put all the videos on mutual inductance and transformers in ac circuit analysis in the math and science app please.

[@grzegorzswitek4293]

Is it contradict entropy?

[@khadijahasim8990]

tell me the answer when you find it ;p

[@AmericanVintagePostcards]

I had distilled water outside at 10 degrees F overnight tap it and never freezed. Why that?

[@Albertmars32]

Suggestion to make a video about neutrinos.

[@donc-m4900]

How long did you put the 2 bottles of water in your (normal home) fridge/freezer?

[@Unknownentityanon]

Next time, use a dark background. It will show better. 😊

[@felixcat4346]

Could you put some ethanol in a 5-gallon Gruff phone and lighted please

[@59vaughn]

I've seen beer do that to...the best taste...😏

[@tedanderson463]

Sir ... Why does water change from solid to liquid... Or to a gas... I'm not asking because I don't know about 32° Fahrenheit and 212 degrees Fahrenheit... But here's a question define the word .....cold.... You may know what I'm getting at.... It seems so complicated to me that if molecules and atoms slow down they become coldness... But why? Why did they become cold? .... If you subtract 32 degrees from 212°.... You get 180 degrees... So out of all the different temperatures... Waters liquid state can only be within a small window.. really that's irrelevant to what I'm curious about. What is the name of the energy that caused water to get cold . Please don't say refrigerator.

[@killpidone]

Cold is just the absence or lack of heat (or less energy) in the system. Much like pressure, heat is always "trying to even out" so high moves to low. Heat will move to something with less heat. Relatively something with less heat we refer to as "colder" vs something relatively with more heat as "hotter".
A fun experiment you can do is measure the temperature of a piece of metal. You'll find that the piece of metal is the same temperature as air in the room, however it feels "cold" to your hand. It's not that the metal is cold, but that it's a good conductor of heat, and you're warmer than room temperature, so the heat from your hand is transferring to the metal, which in turn transfers to the air in the room over time.

[@tedanderson463]

@@killpidone I guess that's an excellent answer to a question that I did not ask... That was interesting though..... Let me ask my question like this....... If water solidifies 32°what's going on with the molecules and atoms at at 32.1 degrees.... And what is going on with the atoms and molecules at 31.9999999999999 degrees. And why did it solidify.

[@edealexander3693]

So why haven't I experienced this mistakenly?

[@pinakgohil]

Sir do you know *Glass is a super-cooled water* 😊

[@Unknownentityanon]

You mean fluid.

[@thatomofolo452]

Will melt

[@Bl4D_3]

I actually did this……..with Gatorade

[@drumtwo4seven]

Nice 👍 💦

[@MathAndScience]

Thanks ✌

[@thewanderingamerican5412]

32 degrees Farenheit or move to Europe.
