[edit] Interparticle spacing
The average interparticle spacing is roughly (V/N)1/3. Suppose we had a cube that was length L on each side, and the inside was divided into cubes of length s on each side, each little cube containing a particle, so we know that the average interparticle spacing is roughly s. The volume of the cube is V=L3, the number of particles in the cube is N=(L/s)3 so the average interparticle spacing is s=(V/N)1/3.
