Anomalous expansion of water | Class 11 (India) | Physics | Khan Academy

Why does ice float on water?
You may already know that ice is less dense than water, but why? Usually, solids are denser than liquids.
In this video, we will explore the Anomalous expansion of water, and understand what makes ice less dense than water. We also look at some other consequences of this phenomenon.

Now, at the end of the year I understand what is meant by anomalous behaviour of water
The video was so helpful 😊👍🏻

[@almuksidalamalvi5860]

Perfect video before my test.

[@sakariyehhhhhhjcbnnmmmsuld9311]

Yeah really

[@prabhuprasadpattnaik4449]

Now this concept is crystal clear

[@knadeemkhan]

every time i have asked anyone ( this is atleast 10 years ive been confused)why ice is less dense than water they have given me a complicated answer that has always confused me and never really answer my question .Furthermore this question was asked by my examinor in viva...Thankyou is an understatement.!

[@ShreyaSingh-ke7vg]

Awesome video!!! Understood this concept clearly which seemed impossible!! Thanku soo much!!! ❤

[@AdwaithJayakrishnan]

Amazing explanation sir, truly fascinating to know that ice is actually less dense than water. I hope to remember it forever and I'm glad you were the one who taught me this. the explanation was very clear!

🎉👍👍👍👍👍

[@anchalgupta8651]

Hey i do have a doubt
What happens if we cool it further than 0°c??

[@KhanAcademyIndiaEnglish]

Water crystallizes into ice, but more importantly for us, it keeps expanding. This is why ice has less density than water.

[@ridax4416]

Perfect explanation thank you so much

[@krishnaphysics4102]

👍

[@mdmukarramali5107]

Thanks sir it was too beneficial

[@kageyamatobio6977]

Thank you so much you explained greatly!! :))

Tysm Khan Academy.. i wasn't really gonna comment but the way y'all explain is so good that i had show a mark of appreciation!✨
Y'all deserve a lot more🌟🖤

[@ricktapio4834]

My question is does this mean it's more efficient to store water at +4 degrees than when it's frozen ?

[@ervivekchoubey]

You will have to figure that out because to maintain 4°C you will have to use electricity or fuel in addition to a good insulator.

[@AnuragSingh-cm3pb]

Very nice explanation
