A few crystals of potassium permanganate in water will diffuse and turn the water purple. Stirring some sugar into tea will help it diffuse quicker. Leave a soda bottle open and the carbon dioxide bubble will diffuse and leave it flat. When cooking pasta, the water diffuses into the noodles, making them bigger and moister. If you water wilted plants, the water will diffuse into the plants and they will get firmer.

Heat is diffused during heat conduction, such as a mug getting hot when a hot liquid is placed in it. In leaves, oxygen from the leaf cells diffuses out to the air. Alloys are examples of diffusion, as in copper being diffused in a copper alloy. If two metal blocks are pushed tightly together and remain like that for several years, one metal will diffuse into the other metal. In the crystal solid state, lattice diffusion occurs, which means the atoms move within the lattice structure. In a leaf, carbon dioxide diffuses from the air spaces between mesophyll cells to the chloroplast.
