Concept introduction:
Intermolecular forces operate between the molecules so changes with change in the phase and effects with physical properties of the substance. In intermolecular forces, the bond is formed between two molecules with partial charges that are present relatively far away from each other.
Viscosity is the quantity that determines the resistance of the liquid to flow. Both liquids and gases can flow but gases have high viscosity than liquids. Viscosity is directly related to the intermolecular forces and therefore increases with increase in the intermolecular forces.
The formula to calculate the intrinsic viscosity is as follows:
Here,
(b)
The intrinsic viscosity of benzene is to be calculated. Also, the use of intrinsic viscosity in a given solvent to determine the molar mass of any sample of that polymer is to be determined.
