It is observed that water will wet a clean glass because the?
cohesion of water to glass is stronger than the cohesion of water molecules
adhesion of water molecules is weaker than the cohesion of water to glass
cohesion of water to glass is weaker than the cohesion of water molecules
adhesion of water molecules is stronger than the cohesion of water molecules
Explication
When the adhesion of liquid molecules to the glass is more than the cohesion of the liquid, the liquid will wet glass.
