**Title: Understanding Power Cycles: Energy Transfer and Temperature Effects** **Problem Statement:** A system undergoes a power cycle while receiving 1450 kJ by heat transfer from a thermal reservoir at a temperature of 750 K and discharging 560 kJ by heat transfer to a reservoir at: a) 250 K, b) 380 K, or c) 460 K. For each case, determine whether the cycle operates: - Irreversibly, - Reversibly, or - Is impossible. **Discussion:** This problem requires an analysis of thermodynamic cycles and their efficiency based on the temperatures of heat transfer. Calculating the efficiency and checking for compliance with the Second Law of Thermodynamics can help determine whether each scenario is possible, irreversible, or reversible.
