5. (10 pt) Complete the following statements (You might explain your rationale briefly if you wish): a. Particles in cohesive powders don't move individually and flow rather in chunks, because 1. The forces between the particles are larger than the weight of the particles. ii. The weight of the particles is larger than the forces between the particles. ili. None of the above b. becomes necessary to break up the lumps in cohesive mixtures. i. High RPM (revolutions per minute) il. Shear Stress iii. Many blender revolutions iv. All the above c. Tapped density of a powder is always its bulk density. I. more than ii. less than iii. equal to d. The greater is the cohesion of the powder, is the difference between the dilated density and the tapped density of the powder. i. the lesser ii. the greater ii. None of the above e. Electrostatic charging of powders can cause
