JEE Main 2024 (Online) 30th January Morning Shift Chemistry - Thermodynamics Question 30 English

An ideal gas undergoes a cyclic transformation starting from the point A and coming back to the same point by tracing the path A→B→C→A as shown in the diagram above. The total work done in the process is __________ J.

Step-by-Step Verified Solution

Work done is given by area enclosed in the P vs V cyclic graph or V vs P cyclic graph.

Sign of work is positive for clockwise cyclic process for V vs P graph.

W=12×(30−10)×(30−10)=200 kPa−dm3=200×1000 Pa−L=2 L−bar=200 J
