Question

Where will the amount of dissolved oxygen be more, in a mountain lake at
10,000 ft at 50^oF or in a lake near sea level at 50^oF?

• A. In a lake near sea level
• B. Amount of dissolved oxygen is same in a mountain lake and in a lake near sea level
• C. Cannot be predicted
• D. In a mountain lake

Answer 1

The correct option is A

In a lake near sea level

At higher altitude pressure is low. Lower is the pressure lower is the solubility of gas. Since a mountain lake is at higher altitude solubility is less as compared to lake at sea level.
