Final answer:
A plot of η/η0 versus φ in Einstein's Law of Viscosity shows the relationship between the relative viscosity and the volume fraction of particles in a suspension.
Step-by-step explanation:
A plot of η/η0 versus φ in Einstein's Law of Viscosity shows the relationship between the relative viscosity (η/η0) and the volume fraction (φ) of particles in a suspension. This plot is used to determine the flow behavior of suspensions, where η is the viscosity of the suspension and η0 is the viscosity of the solvent.
In general, a suspension with a higher volume fraction of particles will have a higher relative viscosity. This is because the particles create resistance to flow, leading to an increase in viscosity. The plot can provide insights into the behavior of suspensions and can be used to study phenomena such as sedimentation and the flow of colloidal systems.
