Question

Why is pressure on a concave side of a liquid drop or bubble more than that on its convex side

Open in App

Solution

Surface tension:

It is the tendency of a liquid to oppose the external force.

In the case of a liquid surface in curved shape, the expression for excess pressure between its curved surfaces (concave and convex) is

$p = T (\frac{1}{R_{1}} + \frac{1}{R_{2}}) H e r e, T i s s u r f a c e t e n s i o n, R_{1} a n d R_{2} a r e t h e r a d i i o f c u r v a t u r e o f c u r v e d s u r f a c e s .$

The reason for more pressure on concave surface is the property of surface tension.
