One mole of an ideal monatomic gas undergoes a cyclic process as shown in the figure. The total heat supplied to the gas is :

Asked in Re-NEET 2026 · Work as the Area of a Closed Loop

• (1) 400 J
• (2) 500 J
• (3) 600 J
• (4) 800 J

Step-by-step solution

Why the other options are wrong

• (1) No single slip gives 400 J; the loop spans 200 N m⁻² by 3 m³.
• (2) No single slip gives 500 J; the loop spans 200 N m⁻² by 3 m³.
• (4) No single slip gives 800 J; the loop spans 200 N m⁻² by 3 m³, so the net work is 600 J.
