Question

    Pieces of camphor placed on water move about rapidly.

    This is because of -
    A diffusion Correct Answer Incorrect Answer
    B viscosity Correct Answer Incorrect Answer
    C surface tension Correct Answer Incorrect Answer
    D capillarity Correct Answer Incorrect Answer

    Solution

    The Camphor slowly dissolves in the water lowering the latter’s surface tension in the immediate neighborhood. The stronger pull exerted by the uncontaminated portion of water brings about a movement of the surface and the camphor particles are carried along with it.
