The anomalous expansion of water refers to its unique behavior when it's cooled below 4°C, where it actually expands instead of contracting like most other substances. This property is consistent regardless of altitude. However, at higher altitudes, the atmospheric pressure decreases, which affects the boiling and freezing points of water but doesn't change its anomalous expansion behavior.
At high altitude as there is low pressure water molecules will go more apart from each other so for analmous expansion we need to decrease temperature even more than normal conditions for water molecules to come closer to form ice
The fish did not freeze because as you explained the ice is less dense than the water and is poor conducter of heat so it rises upwards and reflects the heat that's why the temperature of the fish water below the ice remains warm So, fishes at places even cold than -2 degree Celsius des not die by freezeing in the cold water Thanks for explaining everything about it chetna mam I love Byju's it's my favourite classes 🤗🤗😊😊
Anomalous expansion increases with altitude. This is because as you move higher, there're lesser air molecules which contributes to lesser atmospheric pressure. This means there's less force on the water molecules. Thus, they have more freedom to expand.😊
Imagine that you are at a particular higher altitude and you have wonder with you. How what you do is that you lower the temperature of water below 4 degree Celsius. As we know that at such higher altitudes the pressure is lower and the temperature is also low so, what would happen is that now the water needs more pressure to reach below 4. So now, water happens to be more denser than the water at surface exactly below that altitude.
Ma'am I have a question: If oxygen already balanced due it's self bonding that is O2. Then why it reacts with other elements because it already achieve noble gas configuration that is O2. Similarly in case of Cl2. Plzz ma'am make a video on this problem!
The general dence of cold water remains unchanged until 4o C The density of water gradually increases as you cool it When you reach 4oC its density reaches a maximum The effect of this expansion of water is that the coldest water is always present on the surface Since water at 4oC is the heaviest this water settles on the bottom of the water body and the lightest the coldest layer are on the top layer So in the winter the top of water is always the first to freeze over ice and water both are bad conductors of hea this top layer of ice insulates the rest of the water body from the cold of the winter. Thanks mam for this amazing conceptual video 🤩🤩I eagerly wait for it and it's so cool👍🏻👍🏻
Mam I have a question *"Science says that energy is neither be created and nor be destroyed only can be transferred from one body to another". Energy comes from where ⁉️⁉️⁉️
There will not be special chage in it the only thing that happen it that the frozen surface layer of water will frigid at little bit higher temperature 🌡️ than at the sea level. else it nothing change will seem.
In high altitude with lower atmospheric pressure, I guess water will boil at less than 100C and freeze at more than 0C. Correct me please if I'm wrong.
Mam we want to know about that everything is made up of atoms but why and how their states are different like solid, liquid, gas and plasma... Please Explain us...
Pressure is lower and also the temperature is lower at high altitude and water needs enough pressure to be below 4°C and water is now appearing to be much denser than water at surface exactly below that altitude

when i tell you this was the only video that helped me understand what anomalous expansion of water was, i am being for real.
U guys r taking the education and curiosity on another level
Byju's is the Apple of education.
I don't know that we can learn like this
Proud of you
I love byju's

The fish did not freeze because as you explained the ice is less dense than the water and is poor conducter of heat so it rises upwards and reflects the heat that's why the temperature of the fish water below the ice remains warm
So, fishes at places even cold than -2 degree Celsius des not die by freezeing in the cold water
Thanks for explaining everything about it chetna mam
I love Byju's it's my favourite classes 🤗🤗😊😊
Miss, you explained it in a very different way, I don't have words to praise you. 👍

Thank for the effort :)
Byju's is the best app to learn world's best app to trust
She makes the topics more and more interesting thank you miss

Thanks mam for this amazing conceptual video 🤩🤩I eagerly wait for it and it's so cool👍🏻👍🏻
Which class are you studying?
Very nice explanation chetna mam❣️❣️👌👌
I love byju's videos 📹 😍
Thanks. A good explanation
Thank you iam a topper now😊❤😊❤😊❤😊❤🎉🎉🎉🎉
Mam, with your explanation I understood very nicely.Thank you 😊😊
Mam I have a question
*"Science says that energy is neither be created and nor be destroyed only can be transferred from one body to another". Energy comes from where ⁉️⁉️⁉️
I am your sincere student.....i am so glad and proud to see you here.God bless you... i pray for your longivity.Thanks a lot! :)
It's my pleasure. Thanks for your love and support :)
byju is really best application for students
I am your sincere student Vidhi.
Why is there no gravity in space?
Definitely this i something interesting and we will make a video about this :)
The figid layer at the surface of water at altitude will be of 2-3 degree celcius whereas at sea level it is of 0 degree celcius
Just an example for the question, that's the reason why there is usually snow at the top of mountains, that's what I understand
Nice teaching 👍
how do you make such good videos 🤔
One question to ask why there's space between water molecules in ice?
Due to the particular arrangement that arises due to H-bonding!!!.
Wow this is a good video 🎉
Very Helpful Videos
There will not be special chage in it the only thing that happen it that the frozen surface layer of water will frigid at little bit higher temperature 🌡️ than at the sea level. else it nothing change will seem.
Thank you madam
You’re welcome 😊

👍 awesome
I am your sincere student Vidhi. Where does the sound of Thunder come from?
Interesting!! Let's see what others have to say about this :)
Why water pipes burst in winters ?
It really fantastic
Thanks a lot for the information
Keep sharing such videos
Mam we want to know about that everything is made up of atoms but why and how their states are different like solid, liquid, gas and plasma... Please Explain us...
Thank you ma'am for this amazing explanation.😇👍
Thanks for this knowledgeable video🇳🇵🇳🇵🇳🇵🇳🇵
So nice of you
Beautiful video
Cool
Awesome byjus ❤️❤️
Nice explanation
Lovely vedio
Pressure is lower and also the temperature is lower at high altitude and water needs enough pressure to be below 4°C and water is now appearing to be much denser than water at surface exactly below that altitude
I don't know the name of mam but she explains really fantastic
💜💜
Her name is chetna
Thanks a lot :)
Her name's Chetna sis haven't you seen her Channel
At higher altitudes, te temperature is much lower. It must be lesser than 0 C. So anomalous expansion probably won't take place...
Anamolous behavior can be perceived on altitude before the sea level with a temperature difference of 2C - 3C
Why do we use only crude oil products as fuel in vehicles please answer my question mam
Thankyou
Welcome
We want to know more
Wow!!
Why does water behave abnormal what causes ot
The most common question_why ice floats on water?
Cooll
Earth got it's ice caps after life started on Earth
i love ice
