Which of the following is a result of Surface tension ?
-
- Gravitational pull
- Viscosity
- Capillary action
- Radiation
- Gravitational pull
Correct Option: C
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.
