Problem: The molecular models of glycerol and 1-propanol are given here.Do you expect the viscosity of glycerol to be larger or smaller than that of 1-propanol?

FREE Expert Solution

Viscosity is a physical quantity that measures the internal friction in a fluid. In other words: It is the resistance of a fluid to flow.


Viscosity corresponds to the concept of thickness in a fluid.


For example honey is more viscous (or thicker) than water.


Viscosity of a liquid depends upon various factors such as the strength of intermolecular forces, molecular shape/size and temperature.
