SURFACE TENSION How many drops of water can a penny hold? Cohesion is the tendency of molecules within a substance to ‘stick together’. Water has a high cohesion because of hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it. . ‍ follow @sciencewithhazel . ❤️ tag your friends . credit: YT/Ryan DeLaHaye
