MHT CET 2025 Physics question
A polyatomic gas at pressure 'P', having volume 'V' expands isothermally to a volume '3 V' and then adiabatically to a volume '24 V'. The final pressure of gas is (for moderate temperature changes)
Answer: (D)
Solution
Isothermal stage: . For a polyatomic gas at moderate temperature (nonlinear molecule, 3 translational + 3 rotational degrees of freedom) . Adiabatic stage: $^γ = ^γ ⇒ =
