Answer :
Final answer:
Colder water dissolves gases better than warmer water due to increased solubility at lower temperatures. Factors like pressure, temperature, and salinity affect the solubility of gases in water. Dissolved oxygen and CO2 concentrations in ocean water depths vary based on biological processes, temperature, and pressure.
Explanation:
Colder water will dissolve gasses, such as oxygen, better than warmer water. This is because solubility of gases increases with decreasing temperature. For example, in cold ocean water, more CO2 dissolves, making it a major reservoir of dissolved CO2 in the ocean.
The solubility of a gas in water is affected by factors like pressure, temperature, and salinity. Cold water can hold more dissolved gases than warm water due to increased solubility at lower temperatures. For instance, oxygen levels in ocean water decrease with depth, with the highest content near the surface where atmospheric exchange and photosynthesis occur.
Dissolved oxygen and CO2 concentrations vary in ocean water depths, influenced by biological processes, temperature, and pressure. Cold, deep water typically holds more dissolved gases than surface water. The Pacific Ocean contains more CO2 in deep waters compared to the Atlantic due to various factors like age and biological activities.
