Questions
P–V plots for two gases during adiabatic processes are shown in 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
detailed solution
Correct option is B
For adiabatic process slope of P – V graph at a point (P, V) = γPVAt point A, (slope)1 < (slope)2∴ γ1 < γ2 ⇒ 1+2f1 < 1+ 2f2 ⇒ f1 > f2f1 and f2 are number of degrees of freedom.O2 has degree of freedom = 5.While He has degree of freedom = 3.Talk to our academic expert!
