WebThe particle size of a spherical object can be unambiguously and quantitatively defined by its diameter. However, a typical material object is likely to be irregular in shape and non-spherical. The above quantitative definition of particle size cannot be applied to non-spherical particles.

WebWhy are particles spherical? Thus, potential energy decreases with decrease in distance between constituent particles. As a result, from law (1), the particles would try to come as close together as possible.
