Question

It is difficult to express the size of particles in meaningful diameter the reason is that the particles in powder are

Answer 1

Answer:

it is very difficult to measure the particle of powder because it it measured under microscope

Answer 2

Answer:

It is really difficult to express the particle size in meaningful diameter as the particles in powder are irregular in shape.

Explanation:

• The particle's diameter type depends on the method by which the particle's diameter is determined.
• The method used to analyze the size distribution of particles is called sieving.

If we want to determine the particle size, the necessary condition should be that the particle size is uniform like a spherical shape.

But, the particles in the powder have an irregular shape. So, it is really difficult to express the particle size in meaningful diameter.
