oh my god mam such a nice a video, honestly when my chemistry teacher was teaching this topic she also got confused and told us she will teach next day and that next day never came 😂😂🤣🤣 this is the situation of private school , we need teacher like you mam for our better future😊😊
In search of my doubt ...Just I felt on your Channel...and...see...what Wow ....mam... thankyou..so...much. ...your. ... teaching... methodology . With..the...smile..is..good......my..doubts..are...cleared...now...
I wish i could have found this channel earlier...it's so helpful..ur traching is wonderful thankuuuu sooo much❤ u helped me get over my fear of chemistry and gave me a new interest in the subject
Thank you Seema. Excellent presentation. My question concerns Joule-Thomson effect upon stepping down natural gas (CH4) from 3600 psi to 75 psi. The API says the rule is 7°F per 100 psi. So I calculate (3600 psi - 75 psi)/100*7°F= -247°F temp drop. What would happen if CH4 was introduced into a Local Distribution System (for homes and businesses) at 75 psi (through a regulator), but at ~ -177°F due to Joule-Thomson effect? Is it fair to say this very cold gas is ~50x more dense than CH4 at 75 psi @ 70°F? I say this because it seems this gas will want to expand 48x as it heats up to normal temperature. THANK YOU!
you are absolutely awesome ,ma'am.... i wouldn't be able to clear this topic and every single thing of chemistry if it was'nt you ...lot's of love from kerala ..loves you lot
Graphs, in general, have always scared me for some unfathomable reason. Never thought I'd understand one so nicely. Guess now I know what to do whenever I get stuck in another such torture of colourful lines.
Ma’am you have not made a video for the topic ‘kinetic energy and molecular speeds’ which comes just before the topic ‘kinetic molecular theory of gases’. It’s on page 148 of NCERT textbook
Great explanation ma'am . Maam I have a doubt in this graph what is the pressure is it that of the gas or the pressure with which piston is being pushed??
Excuse me maam, I have a doubt...when temp decreases we see that the plateau length is more so we can assume that it takes longer for the gas to completely convert into a liquid, but if temp is less then shouldn't it actually convert faster?
I didn't understand the critical volume. Volume of 1 mole of a gas at Critical Temperature? What does that mean? One mole of a gas always occupies 22.4 L, right? How would a gas exist in the Critical Temperature ? How would stronger intermolecular forces result in higher Critical Temperature?
Why is it that gasses and liquids exist in equilibrium at only low temperature??? I mean what is the reason behind instantaneous change of state at critical temperature and not at lower temperatures?? Can someone please help??
A clear explainations comes only when the person himself has clear concepts ..
Mam is the example

Best video on liquefaction of gases..
In search of my doubt ...Just I felt on your Channel...and...see...what Wow ....mam... thankyou..so...much. ...your. ... teaching... methodology . With..the...smile..is..good......my..doubts..are...cleared...now...
Mam your English is so fluent ,and the way you are teaching is just wonderful. my concept has become crystal clear . Thank you.
OMG!!!!!! I wish i could have been taught by u in class.......Crystal clear concepts....
you are the best and your students were lucky do the service ever
# the coolest chemistry teacher
No one can explain this topic better than the way you did...This is the PERFECT way!
Woww... From concept to accent... Woowww
Her explanation is really too much impressive 👍👍
Mam u and your teaching methodology is too awesome
I wish i could have found this channel earlier...it's so helpful..ur traching is wonderful thankuuuu sooo much❤ u helped me get over my fear of chemistry and gave me a new interest in the subject
best video by the best teacher!!
Very nice ma'am.... outstanding
nicely explained mam. happy.
Last year I watched this video this year also because your teaching style.
Amma how is your health?
Not great. I have another surgery scheduled for 21st. That’s why I haven’t been making videos.
Thanks for asking. Hope you are doing well!
I pray to god, every day for your health. God bless you
Really excellent explanation on liquefaction of gases.Thanks a lot mam
Thankyou mam you teach very nicely so we enjoy the learning
Excellent video
Thanku mam for giving a clear conclusion over liquefaction of gas
Awesome explaination thank u mam
Best TH-cam Teacher
The best explanation of most confusing topic. Must watch it to crystal clear your concept. Salute to mam🙇🙇
I just saw many vedio on liquefaction of gas ,no one completely taught me about this....while your one vedio clearing my all doubts ty mam
It's worth watching the long video for this topic I'm all cleared now tnks for the lecture👏
Excellent💯👍👏
Thanks a ton ma'am,,,
This topic was soo much confusing, but you cleared it very well...
Thanks again
Amma your teaching skills are fabulous.
This show how much knowledge that you have, superb explanation.
hats off mam, was in great problem suddenly found this channel, proved boon to me
ur new subscriber
Very very good video that i have ever seen.
EXPLANATION IS VERY GOOD BUT WHY SO LESS VIEWS
idk dude idk 😟
That's true deliberate lesson, that every parent wish to pay
You are such a nice teacher....really awesome......
Nice video to understand the Andrew isotherm
OMG!!! thank u so much Mam I finally understood this concept
I love the way you teach really keeps me geniis
Loved ur explanation 😊
Great explanation
am through with school years ago, but needed the concept to work on Gas tankers.. This was most helpful... thank you.
What a brilliant teacher mann !!! Massive respect mam!!
remarkable, awesome lecture mam
excellent teaching 👌👌

#Help FULL#
DOUBT: Why Vc is greater than V3 If liquids are incompressible??? Does it mean that liquid compress at low temperature???
You are the best chemistry teacher mam 😊
Mam .Thank u very much for this awsm explanation.....
you are absolutely awesome ,ma'am.... i wouldn't be able to clear this topic and every single thing of chemistry if it was'nt you ...lot's of love from kerala ..loves you lot
thank u maam. I was really confused in this topic. but now I excelled it because of a very conceptual and logical explanation from you!
🌟 🌟 🌟 🌟 🌟 rating from me mam for your teaching
I am in love with ur teaching ma'am
Just awesome
very nice
Very nice explanation...all the concepts are very clear....u ha e an exemplary talent of teaching ....keep it up...
Excellent Ma'am 👍
Graphs, in general, have always scared me for some unfathomable reason. Never thought I'd understand one so nicely. Guess now I know what to do whenever I get stuck in another such torture of colourful lines.
So helpful..
Thank_U ma'am..
🤗🤗
Ma’am you have not made a video for the topic ‘kinetic energy and molecular speeds’ which comes just before the topic ‘kinetic molecular theory of gases’. It’s on page 148 of NCERT textbook
Ma'am, thank you for the brilliant explanation 👏
excellent explanation, I have never had you are the simply best
You are the best
Mam If I saw your video before I will definately join with this channel and your teaching way is simply superb 👌 mam
Big greet from Egypt to you Ms.
Excellent explanation mam 👌👍👍
Thank u mam there is no words and tanks for ur teaching in u tube i recommend ed ur channel for my frnds
Great explanation ma'am . Maam I have a doubt in this graph what is the pressure is it that of the gas or the pressure with which piston is being pushed??

Yes ma'am it is awesomely explained,u made me understand very fast and for very first time❤️
Ma'am I want to know that is this topics - liquification of gas, liquid state, vapour pressure and surface tension deleted from neet?
fantastic g
Mam you didn't explained the reason why co2 has higher critical temp 311 and CH4 has very low of -81.9
Thanks a lot ma'am. I was finding the graph of this topic quite confusing. But you made it clear in no time. ☺😀
Thank you so much, ma'am. You're the best teacher on the planet. God bless you ma'am and get well soon❤️
Really very helpful video
wow 11k subs , its been a journey I've been here since your very first 50 subs
Really excellent
A lot of thanks mam
Your teaching techniques are amazing
Finally my doubts in liquifaction of gasses got cleared
Thank u so much mam
As the temperature goes on decreasing the plateau increases,
Why so?
Perfect😎
Really nice👍
Thank u mam
Totaly slayed it mam
Thankyou ma'am
For such an crystal clear explanation 💙💙
Your explanation is just superb mam.
Thanks for your helpful explanation
very nice mam.....thank you so much..
The day when I accidentally landed on your channel it would be the most memorable day
Iam very fortunate to have this video
thank you so much! such a good video!
I am glad I found this channel ❤️✨
Good explanation
The best explanation for this topic..thank you soo much ma'am!
Mam please complete organic chem!! It's a humble request
I didn't understand the critical volume. Volume of 1 mole of a gas at Critical Temperature? What does that mean? One mole of a gas always occupies 22.4 L, right? How would a gas exist in the Critical Temperature ? How would stronger intermolecular forces result in higher Critical Temperature?
One mole of a gas occupies 22.4 l only at standard temperature and presuure(at 273k and 1atm/1bar pressure).. Hope it helped you
Highly informative. Thanks a lot ma'am
Awesome Mam nice explanation. Thanku so so much
Mam ur explanation is super☺
Mam ...where is the vedio of derivation of Vander walls equation
Why is it that gasses and liquids exist in equilibrium at only low temperature???
I mean what is the reason behind instantaneous change of state at critical temperature and not at lower temperatures?? Can someone please help??
Very much helpful thankyou MAM
