Chapter 21 613 (c) For the isothermal process, we have PV bb aa ′′ = . Thus, PP V V ba a b = F H G I K J == 100 .. atm 10.0 atm a f . For the adiabatic process, we have b b γ = . Thus, V V a b = F H G I K J 251 1.40 atm 10.0 atm a f . P21.32 We suppose the air plus burnt gasoline behaves like a diatomic ideal gas.
