A sample of ideal monoatomic gas is taken round the cycle ABCA as shown in the figure. The work done during the cycle is A sample of ideal monoatomic gas is taken round the cycle ABCA as shown in the figure. The work done during the cycle is

Options

  1. A3pV3 \mathrm{pV}
  2. Bzero
  3. C9pV9 \mathrm{pV}
  4. D6pV6 \mathrm{pV}

Correct answer

A. 3pV3 \mathrm{pV}

Step-by-step solution

ΔW=\Delta \mathrm{W}= area under the p−V\mathrm{p}-\mathrm{V} curve =12×3p×2V=3pV=\frac{1}{2} \times 3 \mathrm{p} \times 2 \mathrm{ V}=3 \mathrm{pV}
