    Question

    Water drops are spherical because of -

    A viscosity Correct Answer Incorrect Answer
    B density Correct Answer Incorrect Answer
    C polarity Correct Answer Incorrect Answer
    D surface tension Correct Answer Incorrect Answer

    Solution

    Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. In the absence of other forces, including gravity, drops of virtually all liquids would be approximately spherical.
