Q
Diffusion
A
The spreading out of particles of any substance, resulting in a net movement from an area of high concentration to an area of lower concentration, down a concentration gradient
2
Q
The equation for Net Movement
A
Net Movement = particles moving in - particles moving out
3
Q
How difference in concentration effects diffusion
A
The greater the difference in concentration, the faster the rate of Diffusion
