Detailed Solution

:
Concept: The ability or inclination of a liquid to come into contact with a solid is known as wettability. This interaction determines at the molecular level whether a liquid will make good contact or bad contact with the solid surface, depending on the needs we have. Adhesion force is the name given to this molecule level contact force.
The molecules of one kind (liquid) interact with the molecules of another type at the surface where the liquid and solid come into contact (solid). Adhesion and adhesive force are terms used to describe the interaction between dissimilar molecules. The harmony between these interactions determines how moist a wettable surface is.
Only by measuring the Angle of Contact between the surface and the liquid can the degree of this interaction, or wettability, be quantified.
Hence, the correct answer is option 4.
