Please help A gas shortage tank is designed to hold a fixed volume and amount of gas at 1.74 atm and 27⁰C. To prevent excessive pressure duebto overheating, the tank is fitted with a relief valve that opens at 2.00 atm. To what temperature (⁰C) must the gas rise in order to open the valve?

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.
