Question

Quizplus · Accepted Answer

Capillary action occurs when adhesive forces between a liquid and a surface are greater than cohesive forces within the liquid. This allows the liquid to climb up a surface, such as a narrow tube or a plant stem, against the force of gravity. Therefore, choice C, which states that adhesive forces are greater than cohesive forces, is the correct answer.
