Gibbs developed the thermodynamic theory of capillarity based on the idea of surfaces of discontinuity. Gibbs considered the case of a sharp mathematical surface being placed somewhere within the microscopically fuzzy physical interface that exists between two homogeneous substances. Realizing that the exact choice of the surface's location was somewhat arbitrary, he left it flexible…

What happens to surface tension upon increasing surface area

WebLiquid surface tension, solid SFE, and the contact angle a liquid droplet makes on the surface are all related. The wetting envelope helps us visualize these relationships and can help us better understand our system and choose materials.
