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.

Answer: It decreases.

Explanation: Solubility of gas in a particular liquid is the volume of gas in ml that can dissolve in unit volume of the liquid to form the saturated solution at the given temperature and under a pressure of 1 atmosphere.

Effect of temperature on solubility of gas:

Solubility of gas decreases with increase in temperature as on heating some gas is expelled out of the solution.

According to Le Chateliers principle , on increasing the temperature, the reaction will shift in a direction where temperature is decreasing i.e. backward direction and thus the solubility would decrease.
