Which method would increase the solubility of a gas? A. increasing the pressure B. stirring the solvent quickly C. increasing the temperature D. decreasing the amount of solvent

The answer to this item is letter "C. increasing the temperature". An increase in temperature will result to a corresponding increase in kinetic energy as kinetic energy is directly proportional to temperature. The increased kinetic energy results to increase movement of gas molecules which allows them for better collision with water.
