Q.

Which of the following is a result of Surface tension?

A. Gravitational pull
B. Viscosity
C. Capillary action
D. Radiation
Answer» C. Capillary action
Explanation: 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.
