    Question

    Which of the following is a result of Surface tension?

    A Gravitational pull Correct Answer Incorrect Answer
    B Viscosity Correct Answer Incorrect Answer
    C Capillary action Correct Answer Incorrect Answer
    D Radiation Correct Answer Incorrect Answer

    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.
