Consider a 1 liter rigid vessel that is initially half full of water and half full of air at room temperature and 5 atmospheres of pressure. If you begin to remove water at a steady rate of 10ml/min, how does the pressure inside the vessel (in atmosphere) depend on time (in minutes) if the process is isothermal? What is the pressure of the system when all of the water has emptied? You can assume no air leaks in the system and air behaves as an ideal gas.
