Class 11 Physics | Surface Tension | #12 Connecting Soap Bubbles of Different Radii | For JEE & NEET

[@akashsudhanshu5420]

Your vidios make me feel "I should take physics after 12th" and my coaching sir make me feel " arts and commerce is better than science" THANKYOU FOR SUPPORTING ME

[@physicsgalaxyworld]

Thanks a ton for your appreciation dear student.

[@swayamprakashkar9664]

Okay so along with physics ,Ashish sir also explains psychology😂👌

[@gigachadkartik]

Fun concept, I just did it on my own. Awesome 😍

[@12akak]

Sir this was too good

[@SumaidSyed]

So,radius of small bubble will decrease and that of larger bubble will go on increasing,so that means pressure inside small bubble will go on increasing and that of larger bubble decrease,so how can pressure in two bubbles become equal?

[@physicsgalaxyworld]

+Syed Sumaid when the smaller bubble surface will be becoming flat at the tube the radius of curvature will start increasing and pressure in it decreases...

[@SumaidSyed]

Thanks but I'm still not getting,why smaller bubble will become flat?

[@physicsgalaxyworld]

+Syed Sumaid It will not be flat... think and follow and imagine if the radius of smaller bubble is decreasing... and decreasing and after sometime it will take the shape of hemisphere with radius equal to radius of the tube... then further if air flows from this to bigger one... the radius of curvature of smaller one will start increasing and will stop when its radius will be equal to that of the bigger one...

[@SumaidSyed]

Sir,thank you very much for this explanation.

[@surbhikhandelwal9256]

What was your rank?

[@rameshbabu101]

Awesome explanation sir...Thank you!!😃😃

[@sapnasah1848]

nice concept,and enjoyed a lot...

[@wdj5922]

just what i needed!

[@alphaiitd1]

Thanks sir, amazing explanation

[@Mr.Tapori]

Mza aayega sir ❤

[@JUSTFUN-wm8mf]

Sir will u explain me that if a inflated balloon is pushed will it burst or pass it's air from one balloon to other ..... As it's not working in my experiment

[@SumaidSyed]

Sir,When the size of larger bubble is increased by pushing more air into it,it's surface area is increasing.Does it mean that the average separation between the surface molecules is increased?

[@physicsgalaxyworld]

+Syed Sumaid No its due to the decrease in thickness of the bubble wall..

[@RoyBoyLab]

Awesome

[@amritsahu860]

sir i had read that when two gas bubbles are connected the smaller one grows bigger. and if two gas balloons are the smaller one becomes further small....can you explain this

[@venkatarohitpotnuru38]

Thank you sir

[@anuradhagarg7233]

very nyc

[@thecurrentaffairs7962]

Sir in balloon example the radius doesnt seem to be equal at any situation but in above example u hv explained that aur flow stops when radius equals

[@JUSTFUN-wm8mf]

Sir would this phenomena works on balloon as I tried so hard but I failed every time...... But on one state when I was doing this experiment I learnt something new that it stabled at a time when the one balloon was big and other was small..... I thinked that it is because the big ballon sucks it's air..... But again when I tried to do it .....By letting the big ballon to be big and on other side the ballon of little smaller size was been placed by me.................... But this time the equilibrium achieved even though the big ballon was not so big but it didn't inflated any further .............. So my question is why did this happend ........... Pls reply as fast as u can sir...

[@HarshvardhanNigam11]

sir how will pressure equate if smaller one gets smaller ? shouldnt pressure be equal when we open the valve ?

[@physicsgalaxyworld]

finally pressure in both will be equal... because radius of curvature of smaller will start increasing when its size will decrease below half...

[@risnya.s.m24]

Sir what will happen to the bigger balloon?

[@tanavposwal]

This is called real learning not entertainment

[@meghnaramaratnam3059]

wow

Hi, Thanks for the video, it's been very useful. However, I don't understand at which point and why, the smaller bubble will stop decreasing until it disappears, as its pressure is increasing. Could you give me an explanation to this. Thanks a lot!

[@physicsgalaxyworld]

Think carefully when the smaller one is decreasing in size and it decreases below the level of hemisphere then the radius of curvature starts increasing and when its radius becomes equal to that of bigger sphere then it comes in equilibrium...

[@ignacioalonsomelero1567]

Okay, gotcha! Thank you very much, I really appreciate it.

[@shoubhiksaha2788]

Is tension in 2 bubbles always same?!

[@anmolkansal7162]

Is the video lecture complete?

[@physicsgalaxyworld]

Yes...

[@aapkamehta]

Can we think like air travelled from high pressure to low pressure

[@physicsgalaxyworld]

Yes...

[@p.ramyashri4110]

Experimental fluid dynamics parts are so non intuitive and interesting ....!

[@laxmiupadhyay7016]

Similar concept was asked in jee advanced...

[@kartikrana1641]

Yup

[@chakradhar5884]

Also in mains

[@rollymishra4074]

Balloon and bubbles are totally different Watch this video kzbin.info/www/bejne/fZqqYZhnqJuhjJY
