Record your results in Table 3.3. coloring spreads every minute for five RIGURE 3.5 Example of diffusion as seen with potassium permanganate dye in agar. The dye diffuses outward over time from a high concen- tration to a low concentration TABLE 3.3 Diffusion Results for Food Coloring in Water Time Distance of Diffusion: Hot Water Distance of Diffusion: Cold Water 1 minute 2 minutes 3 minutes 4 minutes 5 minutes 4 Interpret your results. What effect does temperature have on the rate of diffusion?

Explanation / Answer

Diffusion being the dispersion of molecules throughout a space, is affected by the speed of molecules and the density of the space through which the molecules are being dispersed. The rate of diffusion increase as temperature increases.
