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.

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.

the volume increases
