Question

based on your diffusion simulation lab, what does each curve on the graph indicate about the movement of particles over time? # of red and blue particles time in seconds the particles move faster as concentration differences increase, but never reach equilibrium. the particles stop moving completely once equilibrium is reached. the particles move in one direction only, showing no change in concentration. the particles move randomly but gradually spread out until they reach equilibrium. which part of the compound microscope is used to adjust the amount of light passing through the specimen?

Explanation:

In diffusion, particles move randomly from areas of high - concentration to low - concentration until equilibrium is reached. The graph shows the number of particles over time, consistent with the random movement and spreading out of particles until equilibrium. Particles do not stop moving at equilibrium (they are in dynamic equilibrium), and they do not move in one direction only, and concentration differences drive the process until equilibrium.

Answer:

The particles move randomly but gradually spread out until they reach equilibrium.
