ACTIVITY: DIFFUSIONProcedures:1. Fill one glass cup with hot water. Fill the second glass with cold water.2. Put 1-2 drops of red food coloring in the hot cup, and 1-2 drops ofblue food coloring in the cold one.3. Watch and wait for color to disperse entirely. Observe.4. What would you observe? Which one dispersed quickly? What wouldbe the reason?5. Get two containers. One is wide and the other one is narrow.6. Fill both container with the same temperature of water.7. Put one drop of food coloring in each container and compare their rateof diffusion.8. Observe. Which container demonstrated slower rate of diffusion?Explain.
