Question
p-V plots for two gases during adiabatic processes are shown in the figure. Plots 1 and 2 should correspond respectively to
Options
A.He and O2
B.O2 and He
C.He and Ar
D.O2 and N2
Solution
In adiabatic process
slope of p-V graph,
slope ∝ γ [with negative sign]
From the given graph,
(slope)2 > (slope)1
∴ γ2 > γ1
Therefore, 1 should corresponding to O2 (γ = 1.14) and 2 should correspond to He (γ = 1.67).
