Question

The Viscosity of polymer is ________ than that of pure solvent

a) Lower

b) Higher

c) Zero

d) Same
​

Answer 1

Answer:

a) the viscosity of polymer is lower than that of pure solvent

Answer 2

The Viscosity of polymer is lower than that of the pure solvent.

Explanation:

• The Viscosity of polymer is affected by various factors which include salinity, temperature, concentration, molecular weight, and shear rate.
• The molecular weight of the polymer is measured with the help of a viscometer.
• The molecular weight obtained by this technique is the average molecular weight.
• If the molecular weight is very high for a solution the viscosity of the polymer solution will also be high compared to any pure solvent.

• Viscosity is important for polymer as it is an important characteristic for all materials.

• Any liquid viscosity will affect the flow, heat transfer, and mass transfer.

• In the case of polymers, viscosity is used as a measuring stickiness of the polymer.
