. Most of the nitrobenzene produced in the United States is used to manufacture a chemical called aniline. It dissolves only slightly in water and will evaporate to air. Physical strength and durability depend on this property of polymers.

In the Couette flow a fluid is trapped between two infinitely large plates one fixed and one in parallel motion at. Melting Point and Boiling Point Polymers have a high melting point and boiling point. It is produced in large quantities for use in industry.

Hardness Hard polymers resist the penetration of hard substances into them. Nitrobenzene is also used to. Greater the intermolecular forces longer the chains and hence higher the melting point and boiling point.

Although it applies to general flows it is easy to visualize and define in a simple shearing flow such as a planar Couette flow. Viscosity is the material property which relates the viscous stresses in a material to the rate of change of a deformation the strain rate. Physical Properties of Matter States of Matter Properties of Liquids.

Nitrobenzene is an industrial chemical. We normally think of liquids like honey or motor oil being viscous but when compared to other substances with like structures water is viscous. Viscosity is the property of fluid having high resistance to flow.

Gibbs free energyΔ f G -23724 kJmol. Liquids with stronger intermolecular interactions are usually more viscous than liquids. Specific heat capacity C 75375 005 JmolK.

We have seen the physical and.
