diffusion Flashcards
1
Q
what is diffusion
A
movement of particles from a high concentration to a low concentraction
2
Q
what is a concentration gradient
A
the path from an area of higher concentration to an area of lower concentration
3
Q
what way do particles diffuse
A
down a concentration gradient
4
Q
what process is duffusion
A
a passive process as it requires no energy
5
Q
factors affecting the rate of diffusion
