Question

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 :

Easy

A

8 atm
B

28 atm
C

68.7 atm
D

256 atm

Solution

$In adiabatic process {PT}^{\frac{γ}{γ - 1}} = constant So, P_{2} = P_{1} {(\frac{T_{2}}{T_{1}})}^{\frac{γ}{γ - 1}} = (2 atm) {(\frac{1200}{300})}^{\frac{1.4}{0.4}} = (2 atm) {(4)}^{3.5} = (2 atm) {(2)}^{7} = 256 atm .$
