Question

Ratio between area and pressure in surface tension

Answer 1

Whereas surface pressure often refers to atmospheric pressure at a location on the earth's surface. It is directly proportional to the mass of air over that location. Surface pressure can also refer to the change of surface tension as a function of area of water surface available to each molecule in a solution.

Answer 2

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.
