Plasma (the 4th state of matter) in Hindi for Class 9
HTML-код
- Опубликовано: 19 авг 2024
- In this Science video for class 9 in Hindi we explained what plasma is, how plasma is formed and what the usage of plasma in our daily life are. This is a topic of chapter 1 - 'Matter in our Surroundings' of class 9th science from NCERT.
Before this we knew about the three states of matter, viz., the solid state, the liquid state and the gaseous state. But there are two more states, viz., plasma and the Bose-Einstein condensate.
🔴 What is plasma -
When a gas is sufficiently hot or a high electric field is applied to a gas, its electrons are ejected from the atoms and the gas is said to be ionized. This ionized gas, i.e., the mixture of the neutral atoms, the cations and the free electrons is called plasma.
🔴 Examples of plasma -
Plasma is found inside stars. This plasma is called the fully ionized plasma.
Lightening is another example of plasma. This plasma is called the partially ionized plasma.
Plasma is also used in fluorescent lights and plasma TVs. In fluorescent lights a gas in low pressure is inserted into a tube and voltage is applied in electrodes. Colourful light is emitted from the tube. The colour depends upon the gas inside.
🔴 Gas and colour
Hydrogen - red
Helium - yellow
Neon - orange
Carbon dioxide - white
Mercury - blue
🔴 Few terms associated with plasma
Plasma density - It is the number of free electrons per unit volume
Degree of ionization - it is the part of gas ionized.
Electron-ion collision frequency - It is the number of collision between free electrons with the cations.
Electron-neutral collision frequency - It is the number of collision between free electrons with the neutral atoms.
When the electron-ion collision frequency is larger than the electron-neutral collision frequency, it is called the fully ionized plasma. In other case, it is known as partially ionized plasma.

Really i am a teacher but i was not able to explain this topic much to our students but now everything is clear about this topic.thank you edu next.
Everyone has an unique ability to explain.
You have your own....
And that is brilliant.

I am a Pakistani class 9th student thanks a lot
Sid u are an amazing teacher. Can't tell how much ur videos help.
Thanks.
🙏🙏🙏
Interactive classes always in edunext one class😇😇
🙏🙏🙏
Sir , can you create a WhatsApp group .
..... The voice ... Matches the explanation...... Both above level....
Thankyou so much for sincere efforts
Hats off to you dear educater🙏🙏
Sir apka samjhane ka tareeka bhut achaa...mene itni bar ye toipc pda but first time ab aaya muje samj ...sir apki sbhi vedios osam he .. thnku so much sir...god bless you sir
Sir mai 10th me pahuch gya hu par phir bhi yeh dekh rha hun for knowledge sir kya badhiya explain kiya maza hi agyi 🤩
This is not for 9 or 10 sir gives us whole basic concept of plasma.
Mashallah
Sir you have amazing passion towards physics and also towards teaching, thanks a lot.
I really like your way of explanations.. Huge respect 💖💖
Sir I have a question is that we know that positive and negative charge particles are attract and positive and positive charge particles are repel but sir how the nucleon of an atom contain many protons (positive charge ) stay in the atom without repelltion. Please sir explain that.🧐🧐
Present of neutrons help to bind the protons in the nucleus of an atom hence protons remain in the nucleus of atom without repulsion.
There is a force called strong nuclear force acts between the protons.
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
@@adit8425 thank you but now this now I will get to know about In Nuclear bomb how the proton has separated from the nucleus of an atom 😊 because I am in 10th so I had gain more knowledge and if you are in 9th then I want to tell you that class 9 physics and chemistry are very interesting even if you are a curious person like me then it's more interesting and in 10th science there are not many interesting chapters in physics and chemistry but some chapters like carbon and it's compounds , light , human eye and the colorful world , electricity, and Magnetic effects of current are really interesting and amazing 🧐👍🔥
They have force between centripetal force Electromagnetic force, strong nuclear force, weak nuclear force
Finally ..uploaded your video...
Sir. You are great teacher
🙏🙏🙏🙏
Awesomely explained...

Thanks EduNext Class 9 Sir. I was in very much doubt 🧐🧐. Thanks Sir Once Again ☺️☺️. ❤️❤️. Sir Please Make Video on Bose Einstein Condensate. 🙏🙏🙏🙏
It is very very helpful sir. Thankyou. Sir I have a question that is it necessary for plasma to be hot?
very exciting and easily understandable !! keep up the good work
ONE OF THE BIGGEST COINCIDENCE!! When I was in class 8 I had confusions in the topic thunder.. now while watching this video now when I'm in 9th class God know what came in my mind that I slide the video down and searched for lightening topic so that I could watch that after this lecture.. I had no idea you're gonna discuss about lightening in this video and wow.. you cleared the doubt I had since last session.. thanks sir
Looks .. I'm about get in to the science more deeply after this😲💓💓💓
No words to say for the explanation sir 🙂🙏
Sir its just excellent. Now totally clear about Plasma. But very excited for Plasma TV😄😄😍
Very nicely explained sir! Salute to you 🙏🙏🙏
Sir hat's off to you ! Mind blowing explanation 👍 I really proud of having a citizen of Jharkhand🙏👩⚕️
Best concept of Plasma available on RUclips
Sir, I want to ask one question
At 9:51
You have said that No of negatively charged electrons and positively charged ions are not equal. But how can it be possible, we know that proton and electron have equal charges which is equal to 1.6 x 10-19 C.
And plasma is neutral. So, number of electron and proton should be equal.
He is talking about No of free electrons 😂
@@moneysh19
Except near the electrodes, where there are sheaths containing very few electrons, the ionized gas contains ions and electrons in about equal numbers
This is from wikipedia. You can check
In a plasma, there is an approximately equal number of free electrons and positive ions, resulting in overall electrical neutrality.
And this is result from chatgpt
@@moneysh19
Don't laugh bro.
You are wrong.
Wow your teaching method is too good
Wow! Really helpful video for understanding plasma state and nicely explained..... 🙏🙏
Excellent superb thank you so much for this vedio
Sir your teaching skills are very very grateful thank you so much sir💓💓💓💓💓💓💓💓

Sir what will happen if we continue giving more and even more heat to plasma state?
Hey!!Don't do this,electron will burst.
17:45 its amazing
Why fluorescent bulb emitter red light when filled with hydrogen and yellow light when filled with helium?
Nice info 👍
But Sir, last me tube ke andar gas ko voltage dene se plasma kaise ban jata hai, wahan itna high temp to hota hi nhi hai ?
Nice teaching sir nice explain
🙏🙏🙏
Most of my doubts is cleared by you🙏
Splendid
very nice Sirji
Thank you so much sir
Nice
Thanks a lot
Thank you sir 😊
👏👏👏👏
the concept is out of my mind because, you say about atom, but atoms are in 3,4 chapter, so its very hard for me to relate
Thanku sir 🤠
Yyou are great sir
Nice explanation
Thanku sir, this video helps me lot i am ask lots of teacher but no one was able to clear my dought.
Sir. How the energy of an electron remains constant as long as it revolves in a particular orbit?
Grt explain
