A gas ( $γ$ ) at $P_{1}, V_{1}, T_{1}$ is suddenly compressed to $\frac{V _{1}}{3}$ and then slowly expanded to $V_{1}$ . The final temperature and pressure are:

Options:

Answer:

Solution:

Sudden: adiabatic, $T = 3^{γ - 1} T_{1}$ , $P = 3^{γ} P_{1}$ . Slow expansion is isothermal: $T$ is unchanged and $P$ divides by 3 to give $3^{γ - 1} P_{1}$ . A.
