Diffusion sequence #4 out of 4
Food coloring dispersing in water shows diffusion Dissolved molecules and ions are in constant Brownian random motion This motion causes collisions between molecules which leads to a net movement from areas of high concentration to areas of low concentration diffusion Diffusion occurs until the molecules are evenly dispersed equilibrium In this example equilibrium is achieved when the food coloring is evenly dispersed throughout the water in the glass container Diffusion determines the movements of many important molecules into through and out of living cells
