SUMMARY
The discussion centers on the calculation of final pressure in a vessel containing two gases at different initial pressures, P1 and P2. The correct formula for the final pressure, P_f, is derived using Boyle's Law: P_f = (P1V1 + P2V2) / (V1 + V2), which accounts for the volumes of the gases. The user also seeks assistance in simplifying the entropy change formula, ΔS = nR ln(P1P2 / P_f²), to express it in terms of P1 and P2. The importance of volume and temperature in pressure calculations is emphasized.
