13. Mechanical dispersion is not due to O path length O pore friction diffusion pore size

7.Factors to consider in the selection of appropriate methods in specific gravity determination, excepta.Densityb.Polymorphismc.Physical form of the solidd.Solubility in water or the other liquid8.Specific gravity of a solid in flotation method is compared indirectly with a liquid known specific gravity. When the solid will neither sink or rise in the liquid, the specific gravity of the solid is different as the liquid.a.The first statement is correctb.Both statements are incorrectc.Both statements are correctd. The second statement is correct

Please use phase diagram to explain why micro-segregation and macro-segregation happen during practical solidification.

Proposed a laboratory procedures on how to determine polymer molecular weight based on osmotic pressure and dilute solution viscosity measurements.

27)Viscosity inscresses with increasing pressure true or false

Introducing an impurity into a solid causes: Group of answer choices the melting point to depress due to disruption of IMF pattern in solid   the melting point to increase because more energy is needed to overcome IMFs   a variable effect on melting point

Describe the process of simple diffusion?

Calculate the surface excess of solute given the following data:Molar concentration in bulk solution as prepared:0.100 mol dm-3Molar concentration in bulk solution as determined:0.981 mol dm-3Total volume of solution: 100 cm3Radius of beaker containing the solution: 2.50 cm

How does the melt temperature of the main phase affect diffusion?

Discuss the importance of bulk vs. surface properties of biomaterials. Briefly describe the importance of “biomaterials surface” considering the series of events following implantation of it.
