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