11. Which of the following is a result of Surface tension ? A.Gravitational pull B.Viscosity C.Capillary action D.Radiation
Option C Solution: Capillary action is the result of adhesion and surface tension. Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact, so instead of just the edges moving upward, the whole liquid surface is dragged upward.
