Question

write the dimensions or the size of the colloidal particle​

Answer 1

Particle size is a notion introduced for comparing dimensions of solid particles (flecks), liquid particles (droplets), or gaseousparticles (bubbles). The notion of particle size applies to colloidal particles, particles in ecology, particles present in granular material(whether airborne or not), and particles that form a granular material (see also grain size).
