Question

If the viscosity of a solution is quadrupled, the rms-average distance of a collection of diffusing molecules from their starting point would be _________ over the same amount of time

Answer 1

The viscosity of a solution is quadrupled, the rms-average distance of a collection of diffusing molecules from their starting point would be $\frac{1}{2}$ over the same amount of time.

If the viscosity of a solution is quadrupled then the distance of collection of diffusing molecules would be half over the same amount of time. The viscosity of the molecules is dependent on density of the liquid. It is independent to the volume of the liquid.

What is viscosity?

Viscosity is measure of a fluid's resistance of flow.

The SI unit of viscosity is Poiseuille (PI) is other units ae newton second per square meter or pascal second. The dimensional formula of viscosity is [$ML^{-1}T^{-1}$].

The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature.

η = $\frac{2ga^{2} (Δρ)}{9v}$

Where (Δρ) is the density difference between fluid and sphere tested, a is the radius of the sphere, g is the acceleration due to gravity and v is the velocity of the sphere.

Viscosity Types:

Viscosity is the measure of fluid's friction to it's flow. There are two ways to measure the fluid is viscosity is follows:

• Dynamic Viscosity (Absolute Viscosity)
• Kinematic Viscosity
