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 understand why fish tend to be found in deeper waters of a lake during warmer parts of the day, you need to consider the solubility of gases in water.
The correct statement that explains this phenomenon is:
C. Gases are more soluble at low temperatures.
Solubility refers to the ability of a gas to dissolve in a liquid, such as water. It is influenced by several factors, including temperature and pressure.
In this case, the warmer parts of the day increase the temperature of the lake water. According to the statement, gases are more soluble at low temperatures. This means that as the water temperature rises, the solubility of gases in the water decreases.
When water is cooler, it can hold more dissolved gases. As the temperature increases, the water releases some of these gases into the atmosphere, resulting in lower concentrations of dissolved gases.
Fish rely on dissolved oxygen in the water to survive, so they tend to move to deeper waters during warmer parts of the day where the dissolved oxygen levels are generally higher. Deeper waters tend to be cooler due to limited exposure to sunlight and are therefore likely to have higher solubility of gases, including oxygen.
In summary, the solubility of gases, such as oxygen, decreases with increasing temperature, causing fish to seek deeper waters where dissolved oxygen levels are higher.
