JEE Main 2022 (Online) 29th July Evening Shift Physics - Heat and Thermodynamics Question 125 English Explanation
Lets calculate area bounded by curve

WDEF=WDE+WEF+WFD\mathrm{WDEF}=\mathrm{WDE}+\mathrm{WEF}+\mathrm{WFD} .

amp;=12(600+300)×3+(−300×3)+0WDEFamp;=450 J\begin{aligned} & =\frac{1}{2}(600+300) \times 3+(-300 \times 3)+0 \\\\ \mathrm{WDEF} & =450 \mathrm{~J}\end{aligned}
