1
Q

A
Net movement is the direction the particles move in.
2
Q
Concentration gradient
A
Is the difference in concentration.
3
Q
How do particles diffuse?
A
Particles diffuse by moving around and bumping into each other, spreading out and dispersing.
4
Q
What is diffusion?
A
Diffusion is the net movement of particles from a high concentration to low, down their concentration gradient until they are evenly spread out.
5
Q
How do particles move?
A
Particles move randomly.
6
Q
What happens when the particles are evenly dispersed?
A
There is no concentration gradient.
