According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Therefore, increasing gas pressure will increase the solubility of the gas in solution. However, in contrast to solids and liquids, increasing temperature decreases the solubility of gases in solution. This is because higher temperatures provide more energy for the gas molecules to escape from the liquid phase and return to the gas phase. Therefore, decreasing temperature will increase the solubility of gases in solution. Option B combines these two factors to increase the solubility of a gas in solution.
