A gas ( γ = 1.4 ) at pressure P 1 is adiabatically compressed from volume V 1 to 4 V 1 . The final pressure is:

P 2 = P 1 ( V 2 V 1 ) γ = 4 1.4 P 1 ≈ 6.96 P 1 . A.

A gas ( $γ = 1.4$ ) at pressure $P_{1}$ is adiabatically compressed from volume $V_{1}$ to $\frac{V _{1}}{4}$ . The final pressure is:

Answer:

Solution:

$P_{2} = P_{1} (\frac{V _{1}}{V _{2}})^{γ} = 4^{1.4} P_{1} \approx 6.96 P_{1}$ . A.
