The correct answer is OPTION 3: Wetting.

  • The adsorption of liquid molecules on particle surfaces causes wetting.
  • During a wetting process, two liquids or gases compete for the surface of particles.
  • The solid–vapour boundary vanishes, revealing a solid-liquid interface.
  • When two liquids are brought together, intermolecular interactions occur, allowing the liquid to maintain contact with the solid surface.
  • This occurs when a gaseous or liquid phase is not miscible with the first.
  • The balance of adhesive and cohesive forces determines the amount of moisture (wettability).
