MCQ
Three moles of an ideal gas expanded spontaneously into vacuum. The work done will be .............. $\mathrm{Joules}$
  • A
    infinite
  • B
    $3$ 
  • C
    $9$
  • ✓
    $0$
✓

Answer

Correct option: D.
$0$
d
since the ideal gas expands spontaneously into vacuum, $P_{ext}=0,$ hence work done is also zero.
