When two capillaries of different diameters are immersed vertically in a liquid, the height of the rising liquid

When two capillaries of different diameters are immersed vertically in a liquid, the height of the rising liquid will be higher in the smaller diameter capillary; option [C]. This phenomenon is governed by the capillary action, which depends on the balance between cohesive forces within the liquid and adhesive forces between the liquid and the capillary walls. In narrower capillaries, the cohesive forces dominate, leading to greater rise of the liquid. Conversely, in wider capillaries, the adhesive forces are less effective in pulling the liquid upward, resulting in a lower rise. Therefore, the height of the rising liquid differs between capillaries of different diameters, with the smaller diameter capillary exhibiting a greater rise due to stronger capillary action. This principle is essential in various fields, including biology, chemistry, and materials science, where capillary phenomena play a significant role in processes such as fluid transport, plant biology, and surface science.
