![]() For instance, the flow of honey compared to the flow of water showcases the difference in viscosity between the two liquids. The concept of viscosity can be illustrated through various examples. Viscosity also affects the dissipation of energy in fluid flow, leading to the conversion of mechanical energy into heat. Blood, for example, has a higher viscosity than water, which affects its flow through blood vessels. Liquids with high viscosity flow more slowly than those with low viscosity. Viscosity influences the flow behavior of fluids. The more intense the intermolecular forces and the larger the size of the molecules, the greater the resistance to flow and the higher the viscosity of the liquid. When a liquid is subjected to shear stress, the molecules tend to resist the flow by exerting frictional forces on each other. The viscosity of a liquid is primarily determined by the strength of intermolecular interactions and the size and shape of the molecules. Honey, for example, is more viscous than water due to the stronger intermolecular forces and greater friction between its molecules. The more viscous a liquid is, the more resistant it is to flow. It is the result of internal friction between the molecules of the liquid as they move past each other. Viscosity, on the other hand, is a measure of a fluid’s resistance to flow. ![]() The cohesive forces between water molecules create droplets instead of allowing the water to spread uniformly on the surface.Īnother example is the shape of soap bubbles, which is determined by the balance of surface tension and air pressure. One such example is the formation of droplets on a freshly waxed car. Surface tension can be observed in numerous real-life examples. Advertisements Examples of Surface Tension The cohesive forces within the water create a thin surface layer that can support the weight of small organisms. Surface tension also allows certain objects, like insects, to walk on water. This is why water droplets form nearly spherical shapes. It leads to the formation of spherical droplets, as the spherical shape minimizes the surface area for a given volume. Surface tension has significant effects on the behavior of liquids. The molecules within the liquid are attracted to each other in all directions, resulting in a net force that pulls the liquid surface together. These forces create an imbalance of forces on the surface molecules, pulling them inward and minimizing the surface area. Surface tension arises from the intermolecular forces, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces, between the molecules of a liquid. This force causes the liquid’s surface to contract, minimizing its area and giving rise to the phenomenon of surface tension. It is a measure of the attractive forces among the liquid molecules. Surface tension is a physical property that describes the cohesive force between molecules of a liquid, resulting in the formation of a “skin” or “membrane” at the liquid’s surface. ![]()
