I am struggling to visualize why molecules on the flat surface experience more net inward force than those on a curved surface. If we have 2 surfaces of water which both have the same number of molecules and one is curved, why does the curved one experience less inward force, if anything, to my mind it seems as it would experience more force as it is more compact. Additionally, does bigger curvature imply less surface tension and why?

In: Physics
Water molecules themselves are angled, which will make one side of the molecule more positive, and one more negative. Due to this, water molecules want to curve together as this creates the lowest energy state. A flat surface is trying to pull in due to its surface tension, but the water’s own pressure under the surface keeps it up, therefore increasing the tension on the surface. Think like a spring that wants to retract, but can’t due to being held extended.
