A patient's oxygen tank holds 21.9 L of oxygen (O2) at a pressure of 24.3 atm. What is the final volume, in liters, of this gas when it is released at a pressure of 2.50 atm with no change in temperature and amount of gas?

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
