WebViscosity is a physical property of fluids. It shows resistance to flow. [1] In a simple example, water has a low viscosity, as it is "thin". Syrup and tar, on the other hand, have a high viscosity, as they are "thick". A way to test for viscosity is the speed at which the substance runs down a slope. Syrup would reach the bottom very slowly ... WebApr 8, 2024 · Viscosity is the tendency of a Fluid to resist any change in its shape or Motion. It is a measure of the internal forces of a Fluid. The internal forces or Friction of Fluid comes into play when one layer of Fluid is subjected to move over another layer. More is the Friction; more is the amount of force required to move the layers; this is ... slow glycolysis
