One type of this process involves gas passing through small holes and has its rate given by Graham's Law. Two laws named for Adolf Fick describe this process, and another type of this process occurs in hypotonic and hypertonic cells; that process involves water crossing a semipermeable membrane. Osmosis is a type of, for 10 points, what process in which particles move from regions of high concentration to low concentration?
