P-V plots for two gases during adiabatic processes are shown in the figure. Plots 1 and 2 should correspond respectively to
(A) He and O2
(B) O2 and He
(C) He and Ar
(D) O2 and N2
Correct option (B) O2 and He
Explanation:
In adiabatic process
Therefore, 1 should correspond to O2 (γ = 1.4) and 2 should correspond to He (γ = 1.67).
