You use a full 20 liter compressed air tank with a gauge pressure of 220 atm (at the surface) to fill the balloon from zero volume at depth. Given that the product of pressure and volume stays constant in a gas (as long as the temperature stays constant) and that the pressure inside the balloon equals the ambient pressure, what will be the gauge pressure in the tank once the balloon has been filled to the volume required to lift the boat
