When particles are equally distrubited, diffusion will?
A- continue
B- Go in reverse
C- Stop
D- become permeable
YOu mean equally distributed throughout the medium? The molecules continue to move in all directions (A), but the concentration changes have stopped (C).
I like A better, but I bet a coke somebody will argue C.
for example- when you open a perfume bottle, the particles move from high concentration to low concentration because of defusion. when the perticles are distributed equally what will happen
A,B,C,or D
They continue to move, in all directions, but the concentration gradient is zero, as there will be no concentration changes. Again, looking at what the molecules are doing, I like A as the correct answer, but I suspect your teacher is focusing on C.
As a point of what actually is happening, the movement from high concentration to low is NOT because of diffusion: It is because all molecules are moving. You smell the perfume because of this as the molecules move. We give the term diffusion to this action, and that action (movement) continues even if the concentration has equal distribution.
i think we are focusing on c as well. the only thing I don't understand is, wouldn't DIFFUSION stop but the molecules(particles) keep moving where they are?
To add my two cents worth, here are a number of definitions for diffusion from the web. It should be clear that intermingling (diffusion) doesn't stop when equilibrium has been attained. Hope this helps.
