Alex wanted to observe how diffusion works by adding drops of food coloring to water at different temperatures and measuring the time it took for the color to spread evenly.
What variable was Alex testing in the diffusion experiment?
Based on Alex’s observations, how does water temperature affect the rate of diffusion?
Why do molecules move faster in warm water than in cold water?
Explain how the experiment with food coloring demonstrates the particle model of matter.
If Alex repeated the experiment with boiling water, what would most likely happen?
Identify one real-world application of temperature affecting diffusion, and explain how it relates to this experiment.
