What is viscosity?

On what two factors viscosity of liquid depends ?

An air bubble of radius 5mm rises through a vat of syrup at a steady speed 2mm//s . If the syrup has a density of 1.4xx10^(3)kg//m^(3) , what is its viscosity ?

As the temperature rises viscosity of liquids

As the temperature of water increases, its viscosity

The dimensional formula of coefficient of kinematic viscosity is

An iron ball of radius 0.3 cm falls through a column of oil of density 0.94 g cm^(-3) . If it attains a terminal velocity of 0.54 m s^(-1) , what is the viscosity of oil? Density of iron is 7.8 g cm^(-3)

When do viscosity and refractivity of cytoplasm increase ?

When the temperature is raised, viscosity o the liquid decreases. This is because

Viscosity of a liquid arises due to strong intermolecular forces existing between the molecules. Stronger the intermolecular forces, greater is the viscosity. Name the intermolecular forces existing in the following liquids and arrange them in the increasing order of their viscosities. Also give reason for the assigned order in one line. water, hexane (CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)CH_(3)) , glycernine (CH_(2)OHCH(OH)CH_(2)OH)

A thin plate AB of large area A is placed symmetrically in a small gap of height h filled with water of viscosity eta_(0) and the plate has a constant velocity v by applying a force F as shown in the figure. If the gap is filled with some other liquid of viscosity 0.75 eta_(0) at what minimum distance (in cm) from top wall should the plate be placed in the gap, so that the plate can again be pulled at the same constant velocity V . by applying the same force F ? (Take h=20 cm )
