A compartment measures 3 meters by 5 meters and is 2.8 meters high. A fire raises the temperature from 20oC to 1000 oC. If the starting pressure was 1 atmosphere, what pressure is present at the elevated temperature assuming the compartment remains closed?

P1V1/T1=P2V2/T2
1atm*(3m*5m*2.8m)/293K=P2*(3m*5m*2.8m)/1273K
P2=1atm*1273K/293K
P2=4.3447atm
(1 scientific figure..so 4atm)
