Question

In the lake, fish tend to inhabit deeper waters during the warmer periods of the day. Which explanation most accurately correlates this behavior with the solubility of gases?
A. Gases are more soluble at high temperatures.
B. Gases are more soluble at low temperatures.
C. Solubility of gases increases under elevated pressures.
D. Solubility of gases increases under reduced pressures.

GPT-4o mini · Answer

The behavior of fish inhabiting deeper waters during the warmer periods of the day can be best explained by the relationship between temperature and gas solubility.

The correct answer is:

B. Gases are more soluble at low temperatures.

As temperatures rise, the solubility of gases in water decreases. Therefore, during warmer times, fish may seek deeper waters where the temperature is cooler and gas solubility is higher, allowing them to access the oxygen they need for survival.
