    You have for a fixed mass or moles of ideal gas :

    ---------------------------------------------------------------------

    ( P2 ) ( V2 ) / ( T2 ) = ( P1 ) ( V1 ) / ( T1 ) = PV /T = nR = Constant

    P2 = ( P1 ) ( V1 / V2 ) ( T2 / T1 )

    P2 = ( 800 kPa ) ( 1.000 ) ( 372.2 K / 298.2 K ) = 998.5 kPa <----------------------------
