This is because ALL elements (except for the noble gases) are electronegative to some degree or other; ELECTRONEGATIVITY IS A PROPERTY OF THE ELEMENT which basically says "how strongly does it attract electrons?". I would not go as far as to say that the 'film' is denser than the water strider; seeing as this is a problem that more involves pressure and resistence, a better solution would be to form an equation to determine the pressures at the point of contact between the water strider and the 'film'. These cohesive and adhesive properties are essential for fluid transport in many forms of life. Furthermore, composites are characterized by high strength, low density, enhanced durability, fairly low maintenance, and corrosion resistance. The weight of a needle on top of water pulls the surface tension downward; at the same time, the surface tension of the water is pulling it up, suspending the needle on the surface of the water and keeping it from sinking. it heavily influences the polarity and physiological functions of cells, The property of cohesion allows liquid water to have no tension on the surface. Why is adhesion of water important to life? Because the surface tension of water is high enough to support the weight of the spider but with much lower surface tension, ethanol cant do the same.
