The ability for a substance to dissolve is affected by both temperature and pressure. Temperature As the temperature increases, the solubility of a solid solute also increases, as the solvent can hold more of the solute particles. However, as the temperature increases for a gas, the solubility decreases. As the temperature increases, the gas molecules have more energy and are able to escape the solvent, causing the solubility to decrease. Pressure As the pressure increases on a solution containing a gaseous solute, the solubility of the gas increases. At higher pressures, there are more gas molecules above the solution, which are able to enter and dissolve into the solution. How much KNO3 can dissolve in 50 g of water at 10°C?
