Oxygen supply for a lung related deficiency is supplied to patients from bottled oxygen in gaseous form. The oxygen bottles are considered empty when they are at 2 bar absolute (and at a room temperature of 20 °C) and are filled from a large source of gaseous oxygen at 210 bar absolute and 10 °C and the valve filling the cylinder is closed when the pressure in the cylinder reaches 200 bar absolute. If the heat transfer during the filling process is negligibly small and neglecting velocity and height contributions, calculate the final temperature of the oxygen in the cylinder at the moment of filling valve closure and the mass of oxygen filled into the cylinder. Take the internal volume of the cylinder to be 15 litre. If the cylinder eventually comes to thermal equilibrium with the surroundings at 20 °C what is the final pressure of the oxygen in the cylinder.
