### Understanding Heat Engine Cycles**Problem: Analyzing Two Heat Engines**Two heat engines are represented in the figure below. Engine 1 follows the cycle ABCDA, while Engine 2 follows the cycle ACDA.#### Pressure-Volume DiagramThe diagram below shows the Pressure-Volume (P-V) relationships for the cycles of the two engines:![Pressure-Volume Diagram](#)- **X-axis (horizontal):** Volume- **Y-axis (vertical):** Pressure#### Description of the Cycles- **Cycle ABCDA (Engine 1):** 1. The process starts at point A, moves to point B. 2. From B, it moves to point C. 3. From C, it moves to point D. 4. Finally, it returns from D to point A.- **Cycle ACDA (Engine 2):** 1. The process starts at point A, moves directly to point C. 2. From C, it moves to point D. 3. Finally, it returns from D to point A.#### Question on EfficiencyIf the same amount of heat flows into both engines, then the efficiency of engine 2:1. **Options:** - A. Is greater than to engine 1 - B. Is less than engine 1 - C. Is equal to engine 1 - D. Cannot be compared to engine 1Select the correct option based on the given information.### Further AnalysisTo solve this problem, consider the efficiency formulas and the areas enclosed by the respective cycles in the P-V diagram, which represent the work done by the engines.
