Parts and their functions

• D → E (linear expansion) (D → E (रैखिक प्रसार)) — Work by gas = area under DE = trapezium ½(600 + 300) × 3 = 1350 J.
• E → F (isobaric compression) (E → F (समदाबी संपीडन)) — Work = P ΔV = 300 × (2 − 5) = −900 J (done on the gas).
• F and D: same volume (F और D: समान आयतन) — The gas ends at the original volume (2 m³) — the third side closes the triangle.
• Total work = triangle area (कुल कार्य = त्रिभुज का क्षेत्रफल) — 1350 − 900 = ½ × 3 m³ × 300 N m⁻² = 450 J.
