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 explain the phenomenon of fish being found in deeper waters of a lake during warmer parts of the day in relation to the solubility of gas, we need to consider the factors that affect the solubility of gases in water.
The solubility of gas in a liquid, like water, is influenced by temperature and pressure. In general, the solubility of gases decreases with increasing temperature and increases with increasing pressure.
So, let's evaluate each statement in relation to the solubility of gas:
A. The statement "Gases are more soluble at low pressures" is incorrect. In reality, gases are more soluble at high pressures. This means that as the pressure of the gas above the liquid increases, more gas molecules can dissolve in the liquid.
B. The statement "Gases are more soluble at high pressures" is correct. When the pressure is high, more gas molecules can be forced into the water, increasing solubility.
C. The statement "Gases are more soluble at low temperatures" is partially correct. In general, the solubility of gases increases as the temperature decreases. However, in this scenario, we are considering warmer parts of the day when the water temperature is higher. Therefore, this statement does not explain why fish are found in deeper waters during warmer parts of the day.
D. The statement "Gases are more soluble at high temperatures" is incorrect. In reality, the solubility of gases decreases as the temperature increases. When the temperature of the water rises, the solubility of gases in the water decreases.
Therefore, the correct statement that explains the phenomenon of fish being found in deeper waters of a lake during warmer parts of the day in relation to the solubility of gas is: B. Gases are more soluble at high pressures.
