Question

A sphere with a ratio of surface area to volume equal to 0.15 m-1. A right circular cylinder with a ratio of surface area to volume equal to 2.2 m-1. What results would you expect if these two models were compared in a diffusion test?

Answer 1

Answer:

the rate of diffusion would be faster for the right cylinder

Explanation:

apex

Answer 2

Answer:

Out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test

Explanation:

As we all know, that rate of diffusion is linked to the surface area--to--volume ratio. Larger surface area--to--volume ratio depicts that the surface area of an object is higher that than of its volume. The higher surface area provides higher area for diffusion.

Thus, any smaller object with larger surface area--to--volume ratio will provide higher diffusion rate and hence the time for diffusion will decrease.

While any object with smaller surface area--to--volume ratio will provide lower diffusion rate and hence the time for diffusion will increase.

Thus, out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
