As a result, honey will take longer to flow than water since water has less cohesion and viscosity.Ī classic illustration of viscosity is water running faster than honey. Honey also has more cohesion (the strength with which particles in a fluid attract one another) than water. Honey has a greater viscosity than water, hence it is thicker. Why does Water flow more quickly than Honey? Furthermore, viscosity does not decrease when the number of matter changes, making it an intense feature. As a result, when heated, liquids flow more freely while gases flow more slowly. The viscosity of liquids drops fast as the temperature rises, but the viscosity of gases rises as the temperature rises. Its alternative units are newton-second per square meter (N/s m2) or pascal-second (Pa s). The viscosity SI unit is poiseiulle (PI). The following is a definition of viscosity-Ī fluid's viscosity is a measure of its resistance to flow. Gases have viscosity as well, although it is more difficult to detect in everyday situations. A fluid with low viscosity, on the other hand, flows readily because its molecular structure causes relatively little friction when it is in motion. A fluid with a high viscosity resists motion because its strong intermolecular forces produce a lot of internal friction, preventing layers from moving past one another. It is also a measure of a fluid's thickness or resistance to items traveling through it. ![]() It precisely quantifies the resistance to flow caused by internal friction between fluid layers as they pass one another during fluid movement. Most fluids provide some resistance to motion, which is called "viscosity." Viscosity occurs when there is relative motion between fluid layers.
