SUMMARY
The discussion focuses on calculating the change in pressure and entropy for one mole of an ideal monatomic gas undergoing a quasi-static adiabatic expansion from an initial state of P1 = 1 Pa and V1 = 1 m³ to a final volume of V2 = 8 m³. The relevant equation used is PVγ = constant, where γ (gamma) for a monatomic ideal gas is 5/3. The challenge lies in deriving a second equation without introducing additional unknowns, emphasizing the need for clarity on the assumptions regarding the gas type.
