Brownian motion diffusion is the movement of particles from high concentration to low concentration in a substance this process is essential for life on earth, allowing for the movement of molecular compounds into and out of the cell. Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration the force behind the movement is heat or kinetic energy (also called brownian motion. Diffusion, osmosis, and osmoregulation notes january 23, 2012 diffusion all molecules are in constant random motion (brownian motion) the rate of this motion increases with increasing temperature and decreases with.
Diffusion, osmosis the relationship between heat and motion can be illustrated by observing brownian motion which is the random motion of small particles.
