How does the solubility of a gas change with increasing temperature? It increases. It decreases. It is uniform. The temperature does not affect the solubility of a gas.

The solubility of a gas decreases with increasing temperature. This is the opposite of water whose solubility increases with increasing temperature. Gases are generally more soluble in colder temperatures. For example, oxygen is more soluble in hot water than cold water. This is why hot water can kill fish due to low oxygen.
