In the system shown below, there are 80 x particles, all in region A (the left half of the box). No extra
particles can enter the system. When the system is in equilibrium, what will be true of the particles? -
ANSWER✔ D. In equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and
those numbers will fluctuate but will remain near 40.
The bar chart below shows data for a system with two types of particles, x and y, in two connected
regions, A and B. All of the x particles started in region A, and all of the y particles started in region B.
Which line graph best depicts the data in the bar chart? - ANSWER✔ C. Graph C
Which arrangement of Gizmo settings will produce the highest rate of diffusion? - ANSWER✔ C. the
settings shown in C
Which statement most accurately describes the system of particles represented in the following bar
chart? - ANSWER✔ B. In equilibrium, with more y particles than x particles.
Your lungs are constantly exchanging oxygen and carbon dioxide between your body cells and your
blood cells by diffusion. As you exercise intensely, your body temperature increases slightly. How does
this affect the process of diffusion? - ANSWER✔ A. The rate of diffusion increases due to your slightly
higher body temperature.
