The total pressure is twice as great at 33 feet than at the surface, three times as great at 66 feet, and so on. This pressure pushes in on flexible air spaces, compressing them and reducing their volume. The reduction of the volume of the air spaces is proportional to the amount of pressure placed upon it. When the total pressure doubles, the air ...
