Problem: Liquids can interact with flat surfaces just as they can with capillary tubes; the cohesive forces within the liquid can be stronger or weaker than the adhesive forces between liquid and surface:In which of these diagrams, i or ii, do the adhesive forces between surface and liquid exceed the cohesive forces within the liquid?

We are asked which of these diagrams, i or ii, do the adhesive forces between surface and liquid exceed the cohesive forces within the liquid.


When liquid to liquid cohesive force is stronger, the liquid will stick more to each other.

When liquid to surface adhesive force is stronger, liquid sticks more to the surface than itself.

Problem Details
Liquids can interact with flat surfaces just as they can with capillary tubes; the cohesive forces within the liquid can be stronger or weaker than the adhesive forces between liquid and surface:

(i) A liquid sphere sits on a flat surface. (ii) A liquid spreads out broadly over a flat surface, forming a dome shape.

In which of these diagrams, i or ii, do the adhesive forces between surface and liquid exceed the cohesive forces within the liquid?
