define viscosity in chemistry
Viscosity is characteristic property of liquid, viscosity describes the flow of a liquid. Definition: Viscosity is defined as the resistance in the flow of a liquid Or. Internal friction present between two layers of a liquid which resists the flow of liquid is commonly known as Viscosity. A liquid with high viscosity is thick and flows slowly. A liquid with low viscosity is thin and flows quickly.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of thickness. For example, honey has a much higher viscosity than water.
