mestny [16]

Answer:

Difussion

Explanation:

Diffusion is the result of a totally random phenomenon in which the molecules of a fluid come and go between two vessels that can be connected by a pipe. These molecules travel in a single direction, where the solute is more concentrated to where it is more diluted.

This movement of particles will be modified according to the length or area of ​​the pipe and the concentration of solute. The greater the difference in solute concentration along the tube, the greater the diffusion
