The solubility of a gas would primarily decrease with decreasing temperature. This I believe would be the case, as according to the KMT, as temperature decreases, the movement of the gas particles, atoms, molecules are slowed down, and as a result, less of the substance would be dissolved in the solvent, as the substance would not be moving as quickly, with the other molecules of solvent, and this causes further amounts of the gas to not dissolve.
