Anomalous expansion of water (Boon to aquatic animals in cold regions!!)

This video talks about the role of Hydrogen bonds in the unusual behaviour of water between 0 degrees Celcius to 4 degrees Celcius and how this effect is a boon to the aquatic animals living in very cold regions.

This is the most complete video I've seen. Thanks a lot

[@ramavadhgupta307]

Great sir, wonderful explaining👌👌👌

[@rajashekars6693]

THANKS Sir very much help full

[@lionelmessiroy]

Perfectly what I was searching for

[@rupasonwani861]

Wow ,this is what i was searching for!!😊

[@sangramdasgram5006]

Yes exactly

[@sportsupdates4553]

Very good explanation

[@nikhatjehan]

Very informative sir..

[@biswajitpradhan5616]

Thanks to anamolous behaviour of water so that fishes are not dieing

[@meditalasia9591]

Nice explanation

[@habibasarwar5985]

Thanks a lot!!!

[@gsk0848]

Thank you sir!

[@ck2283]

When temperature increases from 4 degree Celsius to higher temperatures, what will happen to bonds??
(When heating from 0 to 4, hydrogen bond breaks and volume decreases, and when cooled down from 4 to 0, hydrogen bonds are reconstructed.. That's clear for me, thanks a lot)

[@sathidas7534]

Very nice explanation 😁😁

[@sangramdasgram5006]

Yea

[@Craze4Info]

Well prepared and explained. I am a new member of your family from today.

[@MakeMeScientific]

Thanks for watching 🙏
Welcome i am honoured

[@dhwanibro]

the upper layer is frozen, so wouldn't the heat from the layer where fishes are there transfer at some point of time even though ice formation in a slow process?

[@MakeMeScientific]

Ice is a bad conductor of heat so it won't allow heat to escape

[@abdurrauf7525]

What is the purpose of hydrogen bonding between different molecules?

[@sparky2141]

Amazing Video Sir 😊❤️ This is what I was searching for ....but I have a small doubt
When heating.....the hydrogen bonds break..and the Water Molecules come closer......Why don't they go far apart and come nearer only ??

[@MakeMeScientific]

For that cage structure of water has to be studied. Thank you for watching the video and sorry for late reply

[@samiullah3488]

Zbrdust.explain surface tension of water.spherical shape of rain water

[@Shradha-qu5yb]

Sir if the reason for contraction is heating and breaking of H bonds, why doesn't this process continue when the temperature increased further?

[@MakeMeScientific]

Please refer to cage structure theory std 11 chemistry

[@poonamjadhav7190]

sir agar hum water ko 0 Kelvin tak pohacha de toh uski density maximum nahi hogi kya

[@MakeMeScientific]

Correct lekin zero Kelvin reach Karna impossible he

[@poonamjadhav7190]

@@MakeMeScientific par agar uske close bhi jane ka try kare toh kya density badhegi 4 celcius se?

[@rashmirajgire5910]

Why at only between 0-4
Is it because of k.e and p.e?

[@MakeMeScientific]

No. Due to cage structure of water molecules

[@velusp50]

Why this anomalous expansion happens at 4 degrees Celsius.
Do the water molecules absorb or lose energy.
This looks like a quantum jumping

[@mohammedsrivastava5917]

According to your logic density should increase even after 4°C but unfortunately that's not the case!

[@MakeMeScientific]

Thank-you for watching the video. This logic is cage type of hydrogen bonds that only applies between 0 to 4 degrees

[@mohammedsrivastava5917]

Exactly that is my question...why that 4°C not after that?

[@parjanyaarya2641]

Why the bonds break?

[@MakeMeScientific]

Bonds break on heating

[@aaliyakhan7593]

Why do molecules come nearer instead getting away from each other (as the vibration starts in molecules due to kinetic energy) after supplying heat energy

[@MakeMeScientific]

Thank you for watching the video
In ice, the hydrogen bonds form a cage like structure, which is not there in liquid form. That explains why density of water decreases as a solid, unlike what is expected. Liquid water is densest, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached. This is due to hydrogen bonding dominating the inter molecular forces, which results in a packing of molecules less compact in the solid. As you start heating ice, the hydrogen bonds break and the ice melts. All the hydrogen bonds are broken by the time it reaches 4 °C.

Hii

[@jashhindocha1455]

Do we have to draw the graph??

[@MakeMeScientific]

Yes but rough one will be fine.
