STANDARD 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

8 atm

B

28 atm

C

68.7 atm

D

256 atm

Correct Answer

Option D

Detailed Explanation

For an adiabatic process, (T₁/T₂) = (P₂/P₁)^(γ-1)/γ. Substituting T₁ = 300 K, T₂ = 1200 K, P₁ = 2 atm, and γ = 1.4, we find P₂ ≈ 256 atm.
