Question

Equivalent diameter of a particle is the diameter of the sphere having the same

• A. Ratio of surface to volume as the actual volume
• B. Ratio of volume to surface as the particle
• C. Volume as the particle
• D. Surface as the particle

Hint:

The equivalent diameter of a particle is a way of comparing irregularly shaped particles to a sphere by ensuring the same volume.

Answer 1

The Correct Option is C

The equivalent diameter is defined as the diameter of a sphere that has the same volume as the particle. This allows for comparison of the physical properties of different-shaped particles. 
Conclusion: The equivalent diameter compares the volume of a particle to a spherical shape, making option (C) correct.
