Title: concentration gradient
Post by: EvilFrog on 15/08/2009 02:48:06

what caused the water or other substance move down the concentration gradient? Is it a force or others?

No, it just happens because the movement of the particles are all random.

that mean the particle will move automatically until equilibrium achieved?

I'm not sure what you mean.

Given a chance (ie as long as there's nothing stopping them) concentration gradients diaspear.
I guess you could call it automatic- it happens without external intervention.

It has to do with Brownian motion in water. http://en.wikipedia.org/wiki/Brownian_movement (http://en.wikipedia.org/wiki/Brownian_movement)
