Metallic bond is stronger than Hydrogen bond so mercury resist more force than water.

Hence mercury has more dynamic viscosity than water.

Kinematic viscosity of water is greater than mercury due to lower density but dynamic viscosity of water is lower than that of mercury.

Dynamic viscosity
Water < Mercury.

Kinematic viscosity.
Water > Mercury.

Water H2O - 0.890mPa/s.
Mercury Hg - 1.526mPa/s.

Jalal said:   5 years ago
Dynamic viscosity of Hg is greater than that of water whereas kinematic viscosity of water is greater than that of Hg (bcz density is higher for Hg).

The viscosity of water is lower than the viscosity of mercury.
Viscosity of Hg = 0.0015Ns/m^2.
Water = 0.00089Ns/m^2.

Viscosity of water is less than mercury.

Kinemetic viscosity of water is more than mercury.

Faysi said:   5 years ago
The kinematic viscosity of water is greater than mercury because the density of mercury is more than that of water. But dynamic viscosity of mercury is greater than water.

Thank you.

Dynamic viscosity of Water < Dynamic viscosity of Mercury.

Kinematic viscosity of Water > Kinematic viscosity of Mercury.

Here, it is mentioned only viscosity it means here we are talking about the Dynamic viscosity and the dynamic viscosity of water is lower than mercury.

So, the answer will be Option B.
