MDCAT Biology MCQ #996

  1. Question 1

    Q1. A water strider insect can walk on the surface of a pond due to the cohesive forces between water molecules. This phenomenon is:

    • A) High specific heat
    • B) Heat of vaporization
    • C) Surface tension
    • D) Capillary action

    Answer: Surface tension

    Explanation: Surface tension results from cohesion at the air-water interface; capillary action is tempting but involves adhesion to other surfaces.
