At constant pressure, what generally happens to the solubility of solids and gases when the temperature of a solution is increased?

The solubility of gases tends to decrease; the solubility of solids tends to increase, upon increase of temperature.
Explanation:
To dissolve a solid, the forces of attraction between solid particles must be overcome, which process would be favoured by higher temperature. On the other hand, raising the temperature should increase the vapour pressure of the solution, and dissolved gases should outgas.
