I am studying Fire Science Engineering. I have a question concerning my homework. The question is A compartment measures 3 meters by 5 meters and is 2.8 meters high. A fire raises the temperature from 20 degrees C to 1000 degrees C. If the starting pressure was one atmosphere, what pressure is present at the elevated temperature assuming the compartment remains closed? This will be appreciated. Thanks.

If the compartment is closed, the number of moles and volume are constant, so the ideal gas law tells you that
P/T = constant
where T is the absolute temperature.
P2/T2 = P1/T1
P2 = (T2/T1)*P1 = 1273/293 = 4.345 atm
