A fire occurred in a storage room where a steel cylinder of oxygen-enriched air was kept. The pressure of the gas in the cylinder was 300 atm at 20 C. To what value does the pressure change if the temperature increases to 200 C but the volume of the cylinder does not change?

Solution

since volume = cosntant

so T1/T2 = P!/P2

so (273 + 20)/(273 + 200) = 300 atm/P2

so final pressure = P2 = 484.3 atm
