Sir your way of explaining is truly fabulous. I am grateful to you for providing such a quality content

Finally I understand the basis behind the 2σ/r. Thank you for sharing your knowledge, Professor.

You make it look easy, thanks!

Crystal clear, thank u 🙏

Thank you sir❤

OH MY GOD you are back

Very nice explanation Thank you for such quality content

❤️❤️thanks sirr

Hello, Professor. Thanks for your video! Can you explain how to determine the curvature sign? My understanding is that if the curvature center is in the denser phase, then it is positive. Is that right?

I think you have this the wrong way round. We define the capillary pressure as the difference in pressure between the less dense phase and the denser phase, then positive curvature is when the less dense phase bulges out into the less dense phase (think gas and water).

@@BoffyBlunt Thank you so much for answering. I just find the 'dv' part in the first equation you presented slightly confusing and the V=4/3(pi)r^3

@@coldchickennoodles5575 The dV comes from work - the work done from basic physics is PdV where P is pressure and dV is the change in volume. The equation V - 4/3(pi)r^3 is the equation for the volume of a sphere in terms of its radius r.

I understand everything except that the professor can write backwards.
