azotul = gaz biatomic (N2)
argonul = gaz monoatomic (Ar)
la transformare izocora avem
3 + 2 = 5 moli amestec gaze
3/5 parti molare Ar
2/5 partimolare N2
Q = dU + L = niuxCvxdT + 0
Cv(N2) = 5Cv(Ar)/3
=> Q = 2x(5Cv(Ar)/3)xdT + (3xCv(Ar)xdT)/x3
=> 3Q = 10Cv(Ar)dT + 9Cv(Ar)dT
=> Q = 19CvdT/3
=> Q = 6,33CvdT
