Excess pressure inside liquid drop , air and soap bubble | in HINDI | EduPoint

In this video in Hindi we evaluated the excess of pressure inside a liquid drop or air bubble inside a liquid or a soap bubble. It is found that the excess of pressure in a liquid drop or air bubble in a liquid is two times the surface tension of the liquid over the radius of the drop or yhe bubble. Whereas, in case of soap bubble that excess of pressure is equal to four times the surface tension over the radius.
The free surface of the liquid surface behaves like a stretched membrane which tends to contract. The pressure applied by the free surface is cancelled by that excess pressure.

OTHER RELEVANT TOPICS :

Surface Tension - Surface tension is a property of liquid surface due to which liquid surface behaves like a stretched membrane.
If one draws an imaginary line on a liquid surface, the intermolecular force acting across the line per unit length is defined as the surface tension of that liquid surface.

Surface Energy - The surface energy of free surface of a liquid is the increament in potential energy of the surface per unit increment in area.

this derivation actually gave me the feel rather than the derivation done in class.

[AnnuKumari-xyim]

Sir u solve each derivation very easily 🙏🙇thanks

[dheerajdaripaphysics]

Sir your teaching method is very useful to me.

[sparshsarode]

Thanks for the derivation.... Understood Finally...

[akashkoley]

I am a private Tutor also.your explanation is excellent.

[vivekyadavbholu]

thanks sir aap gjb ka smjhate ho wo bhi practically taur p iissse hme smjhne m bhut aasani ho jati h...keep supporting us sir fabolous👍👍👍👍👍👍👍👍👍👍

[nanditagupta]

it was really very gud understood it clearly.

[anjnathakur]

Thanks a lot sir...total cleared my doubt

[arjavgarg]

Very nice. I didn't understand the derivation with balancing force of surface tension so watching this.

Best video for c.tech first year students

[NS-nlpo]

It was so clear...thanks for such good video...

[deepakagnihotry]

thnks sir...ap bot achhi treh smjhate ho..thnks a lot sir..bs ap chemistry ki or video bna diya kro

[anigupta]

It's really a very very good video

[rotas]

Well explained, helped during exam time

[zjpqxcx]

Thank you for the fantastic explanation sir🙂🙂🙂

[debojitroy]

Thanx a lot sir.. Totally cleared my concept
