Initially they are at the same temperature.Finally V2/V1=2 for all of them.
PVgamma=constant
Or,TVgamma-1=constant
So
T2=T1(V1/V2)gamma-1=T1(1/2)gamma-1
T1 is same for all.T2 will be highest for that one whose gamma is least.gamma is least for CO2 here.
If you want to check yourself do it with the formula
Gamma=1+(2/f)
Where f is the degree of freedom and
f=3N-m,where N is number of atoms in a molecule and m is number of constraints.
If it helps please approve.
