consider the following geometric solids.
a sphere with a ratio of surface area to volume equal to 0.3 m.
a right circular cylinder with a ratio of surface area to volume equal to
2.1 m)
what results would you expect if these two models were compared in a
diffusion test?
o
a. the rate of diffusion would be faster for the right cylinder.
o
b. the rate of diffusion would be faster for the sphere.
o
c. the rate of diffusion would be slower for the right cylinder.
o
d. the rate of diffusion would be the same for the two models.

The correct answer is option A. "The rate of diffusion would be faster for the right cylinder".

Explanation:

The rate of diffusion is defined as the amount of molecules that are exchanged from a body to another. The rate of diffusion is directly proportional to the ratio of surface area to volume , where the higher the ratio of surface area to volume the higher the rate of diffusion. In this case, a sphere have a ratio of surface area to volume equal to 0.3 m, and a right circular cylinder have a ratio of surface area to volume equal to 2.1 m. Since the right cylinder have a higher ratio of surface area to volume, the rate of diffusion would be faster for the right cylinder.
