Correct Answer - Option 4 : 10

Explanation

Viscosity:

The relative motion between different layers of liquid or gases is opposed by a force, which is known as the Viscous force and this property is known as Viscosity.
Its S.I unit is Poise.
One poise is equal to 0.1 Pa-s (Pascal-Second).

∴ 1 Pa -sec = 10 poise.

Poise is the CGS unit, whereas Pa -sec is the SI unit.

Note:

Some properties of viscosity are:

This is the property of both liquids and gases.
In the case of liquid, it is seen because of the cohesive force between the molecules of the liquid.
In the case of a gas, it is seen because of the diffusion of its molecules from one layer to other layers.
The viscosity of gases is very less than that of liquids.
No viscosity is there in solids.
Viscosity on an ideal fluid is always zero.
The viscosity of liquids decreases with the rise in temperature.
The viscosity of gases increases with the rise in temperature.
