[@053_abdulhannanbhat8]

Sir you explained this complex topic in a quite easy manner it helped me to understand the topic so to a greater extent so thanks for your help

[@mishking5]

its way too great than any other physics teacher average to average student can be taken to good level by this sort of teaching hats OFF ............ just some kindaa nice music dont take seriously just THANKYOU

[@abiral_chhetri]

A huge respect to you respected Sir...lots of love from Nepal.

[@mansisikarwar53]

Kaash aap hmaare school ke teacher hote

[@anchalyadav6358]

Sir you are a highly respectable teacher......ur explanations are awesome....the way u have explained each and every concept clearly....i have never come across a teacher like you till date....i have prepared my 12th phy through your lectures....as i have taken drop so this year I'm watching all of your 11th lecture....and I've concluded that having a teacher like u...and that too of a sub like phy makes me feel like I'm the luckiest student ever...I Wish i meet u in future with that Dr. Tag before my name.....💐💐💐💐💐💐💐💐😊😊😊Thankyou so much teacher😊😊😊

[@beu_wallah]

Bolo na tumko hm janta hai

[@bhardwajaditya415]

Sir is no more dear

[@krishnaconsciousness4545]

sir you are the best... superbbbbbbb.. you are the real physics teacher sir g... hats of

[@080_priyaagarwal9]

But sir vo P pressure to drop ko chota krne ki koshish krta hai to drop ka size extend kaise ho jaata hai?

[@anush7386]

Awesome explained 😘 bravo

[@vishnudeb5042]

Best physics teacher ever ❤️❤️❤️❤️❤️❤️

[@ishaanarora2966]

sir capilary tube mein surface tension lete time hum imaginary line glass ki brim ko kyo karte hai??

[@KavitaJawale-rs3vf]

Soup jo hum clothes clean karne mai use karte hai vaha surface tension ka solution high hota hai ya low???

[@AnkitSharma-eg7ii]

how many of you like the starting music?

[@saksharsharma1629]

Ankit Sharma I Like the most

[@mandeepmahara9475]

You are best sir....

[@supriyatiwari3147]

what about the negative sign in front of s.t at 36;00

[@teacherbychoice7904]

sir, me apake sub video 2year see dekhata hu, magar , ye surface tension nahi samaja men online ke 10-12 video dekhe he (etoos , edupoint , exam fear ,Khan academy or Baki) magar kisine bhi ye concept deep me nahi sikhai quiry-. top surface ke molecules pe agar net downward force he to o sub molecules niche aane chahiye agar net downward force balance Kiya Gaya he to ko kisane Kiya he? agar top ke molecules niche aa Gaye to top pe kon rahega unaki jagah Kon lega bottom ke molecules unstable nahi he. or bottom molecules unstable hona nahi chahenge. agar bottom molecules uper Lana he to unape work karana padega.ye work Kon karega. please sir Reply me .

[@ruzbihansirkazi1393]

Sagar Shete dude see the molecule is not coming downward so its sure that there might be something that is stopping him to come down or else he would surely come down so it means that there is only one possible reason that it has potential energy/surface energy in it which handles it and not let it go

[@ruzbihansirkazi1393]

And answer of your second part is yes they themselves can't go upward they have to be get caaried by applying heat and that is known as heat of evaporation got it!!!!!

[@dishatiwari285]

+Pradeep Kshetrapal Sir, I have a doubt. When we extend the bubble to calculate the excess pressure we denoted F=PA. Where P is the excess pressure. But sir if we apply force wouldn't the pressure inside the bubble change? And so the Excess pressure that we will obtain would be a difference of internal pressure and the external pressure? Please clear my confusion. Regards.

[@anush7386]

I didnt understand your problem plz explain it again

[@dishatiwari285]

Ashith Salian I mean to say that P is the excess pressure, and P=FA. But, F is the force applied to expand the bubble, so won't the pressure also increase when the force does?

[@anush7386]

The force is applied in direction of pressure

[@ashishsaha5547]

You are wrong, P=F/A or F=PA

[@einsteinthegamer1983]

the area also changes so p=F/A remains constant because as F increases A also increases

[@audiblenews9238]

1:00:49 moment was so nice

sir hum capilarity mein imaginary line glass ki brim ko kyo karte hai??

[@anush7386]

Imaginary line of brim kya hai bhai?

[@targetwithshubham8985]

Nice explanation sir but I want to know that after solving numerical of ncert will I become able to solve all question of hc verma

[@Badrawala]

World best 👍💯teaher

[@ambikathakur8794]

Sir your videos are very good

[@SanjayKumar-mu9qo]

awesomeeeeeeeee!!!

[@ayushghanghoria1673]

sir why dont u open ur branch in mumbai too

[@bheeshamkhatri4541]

sir .... apne boyle's law aur charle's law ka lecture diya ha ? plzzz reply must.....

[@anush7386]

Chemistry ka hai vo sir kyu Bolega

[@shubhamgupta-jl1ew]

kaash ye vedios mujhe mere time pe mil gaye hote

[@jigmetskaldan3616]

Anyone 2021wala here😆😆😆

[@subhranilmaiti9922]

sir is it can be possible that.... Scos*×2¥r=2S/r ...as both are the reason for upward force........sir pls reply

[@sourabbansal7284]

hhk

[@Diego_129]

Nope...as Scos*x2¥r is the upward vertical "force" due to surface tension...while 2S/R ...is the excess "pressure". The point here is force have direction (here upward)..while pressure is tensor quantity.

[@Diego_129]

Also P (excess) = 2S/r...therefore, Force (excess)/area=2S/r.... Force=2S/r*area... Now, according to u... Scos*×2¥r=2S/r*area....✌

[@sourabbansal7284]

brilliant sir

[@kuldeepmishra1426]

please sir send me some vedio of numerical of 9chapter

[@waniabcwani6662]

We want more lectures in regarding to electrical engineering please sir our GATE exam will be get flexibility

sir... mercury mn conduction hoti ha ya convection?..... plzzzz explain........ reply must sir...... plzzzzzzzzzz

[@anushka334]

+Bheesham Khatri in merucry poor conduction take place

[@anushka334]

+Anushka mani tripathi it is a fair conductor.of electricity.and poor conductor of heat
