d all of the above
Solution
Solution Steps
Step 1: Identify the Factors
To determine the factors that influence the amount of gas water can hold, we need to consider the physical and chemical properties of water and gases.
Step 2: Analyze Each Factor
Temperature: As temperature increases, the solubility of gases in water generally decreases. This is because higher temperatures provide more energy for gas molecules to escape from the water.
Salinity: Higher salinity reduces the solubility of gases in water. This is due to the "salting-out" effect, where dissolved salts compete with gas molecules for space in the water.
Pressure: Increased pressure increases the solubility of gases in water. According to Henry's Law, the amount of gas that dissolves in a liquid is directly proportional to the pressure of the gas above the liquid.
Step 3: Conclusion
All three factors—temperature, salinity, and pressure—play a role in determining the amount of gas water can hold.
