Bose - Einstein Condensate (for Class 9) in Hindi
HTML-код
- Опубликовано: 19 окт 2020
- In this Science video for class 9 in Hindi we explained Bose-Einstein Condensate, also known as the 5th state of matter. This is a topic of chapter 1 - 'Matter in our Surroundings' of class 9th science from NCERT.
When a gas of bosons at low densities is cooled to temperatures very close to absolute zero (-273.15 °C), the bosons loose their identity and behave like a single super atom.
In the context of this video I will say that the atoms having total number of protons, neutrons and electrons as an even number, behaves as bosons. e.g., Helium-4 behaves like boson.
Satyendra Nath Bose first sent a paper to Einstein on quantum statistics. Einstein then extended Bose's ideas to matter in two other papers. Einstein proposed that cooling bosonic atoms to a very low temperature would cause them to fall (or "condense") into the lowest accessible quantum state, resulting in a new form of matter.
On 5 June 1995, Eric Cornell and Carl Wieman at the University of Colorado realized a Bose-Einstein condensate in a gas of rubidium atoms cooled to 170 nanokelvins (nK). Shortly thereafter, Wolfgang Ketterle at MIT realized a Bose-Einstein condensate in a gas of sodium atoms. For their achievements Cornell, Wieman, and Ketterle received the 2001 Nobel Prize in Physics.

🙏🙏🙏
Very very appreciable to the explaination of this bose-einstein condensate ..wow..and what a beauty of misterious science //great knowledgeable video and plasma video as well .. really really enjoyed .. 🔥🔥# themisteriousscience
Sir can u plz give me answer
Sir kya hum solid ko directly Bose Einstein condensate Mai convert nhi kr sakhtai.
Thankyou sir, actually I am always interested in learning new things related to science. So when I was researching about states of matter I came across bose Einstein condensate. At that time I didn't know anything but after watching this video, I feel like I got to know a lot. This helped me a lot sir. And I have subscribed you and am looking forward for more such educational videos and I would binge watch all your previous videos too.😊
Ya , that's the thing with me
मैं बहुत दुखी हूं कि पहले से आप की वीडियो नहीं देखा आज देखा तो पता चला इतना अच्छा भी कोई समझा सकता है थैंक यू सर
I myself am a teacher. I found this video helpful.
You are a very great teacher sir, I was searching for this type of vedio but didn't got any!

Thank you sir. Best youtube teacher you are👍👍👍👍👍👍👍
So does that mean that Boson is indestructible ? And does it behave just similar as an atom ( normal atom ) does?
Each and every matter is indestructible( law of conservation of matter) so yes BOSON is indestructible.
I am very grateful that I see your video and that video is knowledgeable
This is not in our Book - Class 9 but I am excited to know about this. I'm a lover of physics 😍
Its chemistry

Sir,What are the modern day uses of Bose- Einstein Condensate?
To create negative mass and negative mass can be used to make time machine ( warp drive space craft ) understood ?
Halanki is par research abhibhi chal rha hai nhi toh ab tak time machine bn chuka hota .
Nice explanation 👍
I understand what is bec exactly thank you sir👍👍
Very helpful
Nice one.
Respected Sir Thank you So Much🙏🙏
Very nice explanation sir
Thank you 🙏
What a explain
Sir u have very good knowledge
It is informative...... 🤘
Thanks sir I am very interested for new things about science for me
U are amazing sir 🙏🏻🙏🏻
I really understood the lesson thanks
Sir class 10 ka physics iit foundation bhi padhaiye na aur naming binary moleculer compound pe bhi plzzz.Vedio was good
brilliantly explained......
Then sir if a question came - how many state of matter are their
So what we wright
3 0r 5
If we suppose that the momentum gets zero
Then what will happen to its wave nature
And how will act
As mentioned, when temperature approaches zero, the momentum is reduced and BEC is formed. It is impossible to go below zero Kelvin (that is why it is called absolute zero), so momentum cannot be reduced to zero.
On a hypothetical note, suppose that momentum goes to zero the net energy of atom will become zero, and so atom will cease to exist. Because atom is nothing but energy fields interacting with each other in a very small space (size of atom). These are 2 types of energy fields (negative, positive).
Superb👍🙏
