P - V plots for two gases during adiabatic processes are shown in the figure. Plots 1 and 2 should correspond respectively to
Text Solution
Verified by ExpertsThe correct answer is:
B
O 2 and He
In adiabatic process, slope of P - V graph is given as, 
For a given P - V graph, slope 
From the given graph,
(slope) 2 > (slope) 1
Therefore, plot 1 should correspond to O 2 ( 
= 1.4) and plot 2 should correspond to He ( 
= 1.67).
