Answer:
c) Cohesive forces stronger than adhesive forces reduce the height of the liquid in the capillary tube, whereas adhesive forces stronger than cohesive forces increase the height of the liquid.
Explanation:
Two types of forces bring about capillary action.
One is <em>cohesion</em><em>, which is the intermolecular attraction between like molecules (that is, the liquid molecules)</em>. The second force, called a<em>dhesion</em><em>, is an attraction between unlike molecules, such as those in a liquid and in the sides of a glass tube.</em>
If adhesion is stronger than cohesion, the contents of the tube will be pulled upward. This process continues until the adhesive force is balanced by the weight of the liquid in the tube.
