1. How does temperature affect the rate of diffusion? Use your experimental results to support your answer.
2. If potassium permanganate was placed in a solution of boiling water (100°C), would the rate of diffusion be greater than diffusion in cold water? Would diffusion of potassium permanganate in boiling water be greater than diffusion in warm water
3. Why does temperature affect the rate of diffusion? (Hint: Consider the relationship between temperature and the speed at which particles move.)
