Final answer:
The solubility of a gas in an aqueous solution decreases as temperature increases.
Step-by-step explanation:
The relationship between temperature and solubility of a gas in an aqueous solution is an inverse one. As temperature increases, the solubility of the gas decreases.
When a gas dissolves in a liquid, it does so due to attractive intermolecular forces between the gas molecules and the solvent molecules. Heating the solution provides thermal energy that overcomes these attractive forces, leading to a decrease in the solubility of the gas.
For example, Figure 11.8 shows that the solubilities of different gases in water decrease as the temperature increases.
