diffusion paths are not straight lines, even though they eventually mix completely.
11. A student states, “Once the colored ink has spread evenly in water, diffusion stops.” Do you
agree or disagree? Justify your answer using particle theory.
12. Why does increasing the temperature of a gas or liquid increase the rate of diffusion? Explain
using ideas about energy and particle movement.
