The pressure of gas inside a sealed container is 2.42 atm at 31.5°C.?
If the barometric pressure is 1.946 atm, to what temperature (in degrees Celsius) must the container and its contents be cooled so that the container can be opened with no risk of gas spurting out?

P1/T1 = P2/T2
=>T2 = P2/P1*T1 = (1.946atm)/(2.42atm)*(31.5+273.16K)
= 245 K = -28.2 C
Hope this helps.
