Three moles of an ideal gas expanded spontaneously into vacuum. The work done will be

Options

  1. Ainfinite
  2. B3 J3 \mathrm{~J}
  3. C9 J9 \mathrm{~J}
  4. Dzero

Correct answer

D. zero

Step-by-step solution

W=pext ⋅ΔVForvacuum,W=\mathrm{p}_{\text{ext }} \cdot \Delta \mathrm{V} For vacuum,\quad \mathrm{P}_{ext \text{ext }}=0 \therefore \quadW=\mathrm{W}=0 \cdot \Delta V=\mathrm{V}=0
