Detailed explanation-1: -This spread of particles through random motion from an area of high concentration to an area of lower concentration is known as diffusion. This unequal distribution of molecules is called a concentration gradient. Once the molecules become uniformly distributed, dynamic equilibrium exists.

Detailed explanation-2: -When the molecules are evenly spread throughout the space, the water will become an even color. This process of molecules moving from an area where there are lots of molecules to an area where there are fewer molecules is known as diffusion.

Detailed explanation-3: -Definition. The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal.
