Diffusion. Tea dissolving in water in a beaker. Chemicals from the tea leaves,which are held in a perforated bag,diffuse throughout the water forming a solution. Diffusion is caused by the tiny,random movements of molecules in a solution. Over time these movements cause the dissolved substance to become evenly dispersed throughout the solvent,without being stirred | |
