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. |
