Heat capacity of air can be approximately expressed as, Cp = 26.693 + 7.365 x10-3 T, where, Cp is in J/mole.K and T is in K. The heat given off by 1 mole of air when cooled at atmospheric pressure from 500°C to - 100°C is

Heat given off by the 1 mole of air is equal to the change in enthalpy of the air during the cooling.
DH = integration (CpDT) limits from the 773.15K to 173.15K.
Heat given off Q = DH = 18.11kJ.
