Surface Tension, Capillary Pressure, and Waterbility (Research Paper Sample)

Surface tension
Surface tension is the ability of a fluid to resist force. The resisted force is the cohesive nature of water molecules. This, makes denser materials than water float. It enables an attractive force to be exerted on molecules of the liquid. Still, it also accomplishes various other critical functions for the ecosystem and humans (Popinet, 2018). Attributable to the covalent bonding of its components, the quality of a liquid's interface offers resistance to an external force.
Surface tension is a derivative of cohesive forces between fluid particles. In cohesion, particles of different kind come together. Because water molecules do not surround the elements at the base of a glass of water in all dimensions, they correspond more powerfully with those directly related to them. (Popinet, 2018). In a liquid, the compressive forces between particles are distributed by all surrounding molecules. Because there are no contiguous molecules above them, some on the surface have a larger force of attraction on their immediate neighbors on and below the surface. From the cohesive nature of the water particles, surface tension can be described as the quality of a liquid's surface that permits it to withstand an external force.
Temperature and impurities affecting the rate of surface tension. Temperature decrease increases surface tension while introducing impurities lowers it. An increase in temperature increases collision of water molecules hence lowering the surface tension by increasing the contact surface forces. Also, introducing impurities in a fluid lowers the surface tension. This is because the impurities affect the intermolecular forces between the fluid and hence lowering the surface tension. Examples
