Multiple Choice Question
During warmer parts of the day, fish will be found in deeper waters of a lake. Which statement best explains this phenomena with respect to the solubility of a gas?
A.
Gases are more soluble at low pressures.
B.
Gases are more soluble at high pressures.
C.
Gases are more soluble at low temperatures.
D.
Gases are more soluble at high temperatures.
C.
Gases are more soluble at low temperatures.
C. Gases are more soluble at low temperatures.
To determine the correct answer to this question, we need to understand the relationship between gas solubility and the given conditions. The solubility of a gas refers to the ability of the gas to dissolve in a liquid. In this case, we are specifically concerned with the solubility of gases in water.
Now let's evaluate each of the given options:
A. Gases are more soluble at low pressures.
This statement is generally true. The solubility of a gas in a liquid usually increases as the pressure above the liquid decreases. However, this does not directly explain why fish will be found in deeper waters of a lake during warmer parts of the day.
B. Gases are more soluble at high pressures.
This statement is generally true. As mentioned earlier, the solubility of a gas in a liquid usually increases with higher pressures. However, this also does not directly explain why fish will be found in deeper waters of a lake during warmer parts of the day.
C. Gases are more soluble at low temperatures.
This statement is generally true. The solubility of a gas in a liquid usually increases as the temperature of the liquid decreases. However, this does not provide an explanation for fish behavior in deeper waters during warmer parts of the day.
D. Gases are more soluble at high temperatures.
This statement is not true. Generally, the solubility of a gas in a liquid decreases as the temperature of the liquid increases. This is due to the fact that as the temperature rises, the kinetic energy of the gas molecules increases, reducing their ability to dissolve in the liquid.
Based on the given options, the most appropriate answer to the question is C. Gases are more soluble at low temperatures. While this statement does not directly explain why fish will be found in deeper waters of a lake during warmer parts of the day, it suggests that warmer water may have lower gas solubility, which could be a factor influencing fish behavior.
It is important to note that fish behavior is influenced by a variety of factors, including temperature, oxygen levels, availability of food, and other environmental factors. While solubility of gases in water can be a contributing factor, it is not the only factor determining fish distribution in a lake.
