Cumulative analysis for determining surface is more precise than differential analysis, because of the_______________?
Correct answer: C. Assumption that all particles in a single fraction are equal in size, is not needed
- A. Assumption that all particles in a single fraction are equal in size
- B. Fact that screening is more effective
- C. Assumption that all particles in a single fraction are equal in size, is not needed
- D. None of these
Explanation
Cumulative analysis avoids assuming that every particle in a size fraction has one representative size, an assumption required in differential analysis. This makes the cumulative method more precise for surface-area estimation.
