I can see this is the fourth illustration on the right column, showing a circle with white circles (water molecules) and purple circles (KMnO₄ particles) that are now evenly distributed throughout the entire container. The purple particles are spread out uniformly among the water molecules, which represents the final stage of diffusion where "particles are evenly distributed throughout the water."
Now I have analyzed all the illustrations and can match them to the correct steps.
The solution is:
- Step 1: A crystal of KMnO₄ is dropped into water → matches with the top left illustration (small purple dot) and top right particle diagram (purple particles clustered together)
- Step 2: Particles begin to break off the crystal → matches with the second left illustration (larger purple area) and second right particle diagram (purple particles beginning to spread out)
- Step 3: More and more particles move randomly away → matches with the third left illustration (further diffusion) and third right particle diagram (purple particles more spread out)
- Step 4: Particles are evenly distributed throughout the water → matches with the fourth left illustration (fully diffuse purple) and fourth right particle diagram (purple particles evenly distributed)
This shows the complete process of diffusion, where particles move from an area of high concentration (the crystal) to areas of low concentration until they are evenly distributed throughout the solvent (water).
Parent Tip: Review the logic above to help your child master the concept of diffusion worksheet.
