How does temperature typically affect the solubility of gases in water?
Understand the Problem
The question asks about the relationship between temperature and the solubility of gases in water. We need to understand how increasing or decreasing the temperature of water affects the ability of gases to dissolve in it.
Answer
Generally, as temperature increases, the solubility of gases in water decreases.
As temperature increases, the solubility of gases in water decreases. This is because the kinetic energy of the gas and solvent increases, causing the gas to escape the solution.
Answer for screen readers
As temperature increases, the solubility of gases in water decreases. This is because the kinetic energy of the gas and solvent increases, causing the gas to escape the solution.
More Information
The relationship between temperature and gas solubility is an example of Le Chatelier's principle. Heating the solution favors the escape of gas into the gas phase, thus reducing its solubility in the liquid.
Tips
It is a common mistake to assume that the solubility of all substances increases with temperature. While this is often true for solids, gases behave differently.
