AIPMT MAINS 2011 Physics Adiabatic Processes MCQ Question
Type: MCQ-numerical-Hard-Class 11
A mass of diatomic gas (γ = 1.4) at a pressure of 2 atmospheres is compressed adiabatically so that its temperature rises from 27°C to 927°C. The pressure of the gas in the final state is
A
256 atm
B
8 atm
C
28 atm
D
68.7 atm
Correct Answer
Option B
Detailed Explanation
Using the adiabatic relation P₁V₁^γ = P₂V₂^γ and T₂/T₁ = (V₁/V₂)^(γ-1), we find P₂ = 256 atm.
