The solubility of a gas in a solvent changes when pressure is applied. Click on the image to explore this activity, which illustrates the relationship between the pressure (P) and the solubility (S) of a gas. In this activity, you can see a sealed container of water and Ny gas. Click on the Run button to see the relative changes in the solubility of N₂ gas in water as the pressure of the N₂ gas is increased and decreased. The values of the pressure and the solubility of gas are tabulated adjacent to the Run and Reset buttons in the activity Part A Click on the Run button in the activity. Watch how the solubility of a gas changes as pressure is increased and then decreased during the run Which of the following statements correctly explain the relationship between the solubility of a gas and its pressure?
