Q139 / 160 · AP EAMCET 2024 (21 May Shift 1) · Physics
Heat energy absorbed by a system going through the cyclic process shown in the figure is
- A$10^7 \pi \mathrm{~J}$
- B$10^4 \pi \mathrm{~J}$
- Correct answerC$10^2 \pi \mathrm{~J}$
- D$10^{-3} \pi \mathrm{~J}$
Solution
For cyclic process,
$\begin{aligned}
& \mathrm{Q}=\mathrm{W}=\text { Area of } \mathrm{p} \text {-v diagram } \\
& =\frac{\pi}{4} \times 20 \times 10^3 \times 20 \times 10^{-3}=10^2 \pi \mathrm{~J}
\end{aligned}$
Hence, the correct answer is option: 'C'.
