In the reported figure, heat energy absorbed by a system in going through a cyclic process is ___________ π J. Numerical answer type. Work it out, then open the answer.

Answer: 100. For a cycle Δ U = 0, so heat absorbed = area enclosed. Radius along P: 10 kPa = 10⁴ Pa; radius along V: 10 L = 10⁻² m ³. Q = π × 10⁴ × 10⁻² = 100π J Answer: 100.

P-V Diagrams & Cyclic Processes

In the reported figure, heat energy absorbed by a system in going through a cyclic process is ___________ $\pi$ J.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 100

For a cycle $\Delta U = 0$ , so heat absorbed = area enclosed.
Radius along P: $10$ kPa $= 10^{4}$ Pa; radius along V: $10$ L $= 10^{-2}$ m $^3$ .
$Q = \pi \times 10^{4} \times 10^{-2} = 100\pi$ J
Answer: 100.
