The cell's energy In Your Notebook Explain how you can demonstrate diffusion by
spraying air freshener in a large room.

By defining diffusion we know that it is a movement of molecules from a region of high concentration to a region of low concentration. What this does is to evenly distribute molecules in a given area. In the case of spraying air freshener in a large room, the volume of air freshener will be evenly distributed around the room. Hence no specific corner in the room will have too much or too little.
