Diffusion. Blue food colouring begins to diffuse in a beaker of water. Diffusion is caused by the tiny,random movements of molecules in a solution. Over a period of time these movements cause the dissolved substance to become evenly dispersed throughout the solvent. This food colouring,for instance,will eventually produce a uniform blue solution without being stirred | |
