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.

THEY BEEN USING THE SAME TES FOR 15 YRS???
Diffusion is the process by which particles or molecules move from an area of higher concentration to an area of lower concentration. When particles are equally distributed throughout a medium, it means that the concentration of particles is the same everywhere. In this case, diffusion will continue to occur because the particles are still in motion and will continue to move randomly in all directions.
Therefore, the correct answer is A - diffusion will continue. Even though the concentration gradient is zero, the particles will still move and diffuse throughout the medium. The particles will not stop moving just because they are evenly distributed.
It is important to note that diffusion is separate from the actual movement of the particles themselves. Diffusion occurs due to the random movement of particles, not the other way around. So, even if the particles are evenly distributed, they will still continue to move, and diffusion will continue to take place.
