It is not safe to put aerosol canisters in a campfire, because the pressure inside the canisters gets very high and they can explode. If I have a 2.0 liter canister that holds 2 moles of gas, and the campfire temperature is 1400^0 C, what is the pressure inside the canister? a) 17500

b) 112

c) 144

d) 274

The air is going to come out because of the low pressure.

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.
