Diffusion
Diffusion describes the process by which particles in a gas spread out due to their random motion. The particles move from areas of higher concentration to areas of lower concentration, resulting in even distribution.
The proper scientific term for the way particles spread out is called diffusion. This is the process where particles move from an area of high concentration to an area of low concentration until they are evenly distributed.
The state of matter affects diffusion rate by changing the spacing between particles. In gases, particles are spread out more, allowing for faster diffusion. In liquids, particles are closer together, slowing down diffusion. In solids, diffusion is minimal due to the fixed position of particles.

Through passive transport
Dissolved particles on one side of the membrane results in the diffusion of water across the membrane due to the need to have the same solution concentration on both sides of the membrane. Water will diffuse from a hypotonic solution to a hypertonic solution.
The higher the thermal energy of a diffused sample AND its solute, the faster the kinetic rate of motion of the dissolved particles, or atoms, and the faster their rate of diffusion throughout the solute.
This is the phenomenon of diffusion.
No, the particles of a solid will not mix by diffusion. Diffusion occurs when particles move from an area of higher concentration to an area of lower concentration, but in a solid, the particles are fixed in place and cannot move around to mix with each other.
