What will be the final pressure of gas in Section B? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Section B undergoes reversible adiabatic compression. Initial volume $V_{B1} = 44.8 / 2 = 22.4\text{ L}$. Final volume $V_{B2} = V_{B1} / 8$. For a monoatomic gas $\gamma = 5/3$. $P_2 = P_1(V_1/V_2)^\gamma = 1 \times (8)^{5/3} = 2^5 = 32\text{ atm}$.
