3.) Process by which smaller particles are put together to form larger masses in which the original particles can still be identified. A Size Reduction B Sieving Size Enlargement D Screening 4.) The cumulative Screen Analysis for determining the surface area of particle is more precise than the differential screen analysis because of the A fact that screening is more effective B None of these assumption that all particles in a single fraction are equal in size is not needed D assumption that all particles in a single fraction are equal in size
