System A liter of seawater at 15° C. A mixture of xenon (Xe) gas and nitrogen (N₂) gas at 1 atm and 22° C. 1.0 g of potassium iodide (KI) and 2.0 L of pure water at 42 °C. Change The seawater is passed through a reverse-osmosis filter, which separates it into 750. mL of pure water and 250. mL of brine (very salty water). An additional 2.0 L of pure N₂ gas is added to the mixture, with the pressure kept constant at 1 atm. The potassium iodide is dissolved in the water.
