What is the relationship between viscosity and density ,

More or less corrugation of the energy landscape leads to higher/lower viscosity For different substances, there is no correlation with density Compare, for example, two almost-n-alkanes C30 and C60 (with the same small fraction of short side chains to reduce the melting point) At, say, 100 °C, the density is almost equal while the ....

Viscosity - Wikipedia

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, syrup has a higher viscosity than water Viscosity can be conceptualized as quantifying the frictional force that arises between two adjacent layers of fluid that are in relative motion...
