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?
The solubility of gases decreases as the temperature of water increases. Therefore, during warmer periods of the day, the deeper waters of the lake may have lower levels of dissolved oxygen, making it more difficult for fish to survive. This is why fish tend to inhabit deeper waters during the warmer periods of the day.
The solubility of gases in water is influenced by temperature. As the water temperature increases, the solubility of gases in water decreases. This means that warmer water can hold less dissolved gas compared to cooler water. In the case of the lake, when the temperature rises during the warmer periods of the day, the solubility of gases in the water decreases. Consequently, the concentration of dissolved oxygen, which is vital for fish survival, decreases in the deeper waters. To obtain sufficient oxygen for respiration, fish tend to inhabit deeper waters where the oxygen concentration is relatively higher compared to the surface waters. Therefore, the decreased solubility of gases in water due to higher temperatures explains why fish tend to inhabit deeper waters during the warmer periods of the day.
