Question

choose the correct answer.
in the summer, what levels of dissolved oxygen would you expect compared to the winter?
equal levels of dissolved oxygen
very high levels of dissolved oxygen in the summer
lower levels of dissolved oxygen in the summer
dissolved oxygen cannot be compared

Explanation:

The solubility of gases in liquids is inversely related to temperature. As temperature increases, the solubility of oxygen (a gas) in water (a liquid) decreases. Summer has higher temperatures than winter. So, in summer, we would expect lower levels of dissolved oxygen compared to winter.

Answer:

lower levels of dissolved oxygen in the summer
