viskoziteti
Viskoziteti is a property of fluids that describes their resistance to flow. It is often described as the "thickness" of a liquid. A fluid with high viscosity, such as honey, flows slowly, while a fluid with low viscosity, such as water, flows easily. Viscosity is caused by the intermolecular forces between the molecules of a fluid. In liquids, these forces are relatively strong, and they resist the movement of molecules past each other. In gases, the intermolecular forces are much weaker, and the viscosity is therefore much lower.
Viskoziteti can be measured in several units, including the Pascal-second (Pa·s) and the poise (P). One Pascal-second
