Diffusivity in water

WebJan 15, 2024 · Dependence of the diffusion coefficient of the water and calcium chloride aqueous solution on the simulation box size. Result are divided by the value of diffusivity, that corresponds to infinite system size D(∞). D(∞) is calculated by fitting the dependence of D(L) on 1/L using relation (1). Blue squares corresponds to the results for water. WebApr 4, 2024 · Diffusion is the movement of particles from higher concentration to lower concentration. Diffusion continues until equilibrium is reached. At equilibrium, concentration is the same throughout the sample. Familiar examples of diffusion are the transport of perfume when it is sprayed in a room or the movement of food coloring in a glass of water.
