We’re asked to determine which liquid demonstrates the greatest capillary rise

Recall that capillary action is the ability of a liquid to rise or flow upward into a small-diameter tube or a capillary.  

  • It occurs when the intermolecular forces of attraction (IMF) between the liquid and the wall (adhesive forces) are stronger than the cohesive forces within the liquid.  
    • Cohesion occurs between similar (like) molecules (e.g. between water molecules)
