Answer:
True.

Diffusion is a process that allows the spread or movement of particles from the region of higher concentration to a region of lower concentration through a semipermeable membrane.
Diffusion only occurs in gases and solution but not in solids, it also occurs only where particles can move freely.
Note: When particles move from the region of higher concentration to a lower concentration, it gives room for even, uniform and random distribution of particles.
