Dissolved oxygen concentration of water question?

Question

In identical containers with identical fish but with different volumes of water (one more than the other), which one would have more oxygen available to the fish? Why?
Thanks for your help!! =)

Answer 1

A lot depends on if the containers are aerated. Logic says that the larger container would have more dissolved oxygen available because there is more water to hold the oxygen.

However, since the containers are identical, the surface area size of the water in the container is probably the same. That will influence the amount of oxygen that actually dissolves into the water.

I recommend that you go to your teacher before class, though not at the last minute, and bring up these two points of view. Ask which of these factors has the most weight. I bet your teacher will tell you which one to choose. Especially if you tell your teacher that you want to understand the question better.

Answer 2

The one with more water simply because more water, more oxygen.
