Solution: 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:
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?
