Answer:

Excess pressure inside a curved liquid surface

Excess Pressure on Curved Surface of a Liquid. We know that the similar molecules of a liquid attract each other by a force of coheasion and force of surface tension, tangentially to the liquid surface at rest. Hence it can be concluded that excess pressure is less on a convex meniscus.

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
