Question

$For space free space expansion space of space the space gas space which space of space the space following space is space true$

$Q = W = 0 and Δ E_{int} = 0$
$Q = 0, W > 0 and Δ E_{int} = - W$
$W = 0, Q > 0, and Δ E_{int} = Q$
$W > 0, Q < 0 and Δ E_{int} = 0$

The correct answer is: $Q equals W equals 0 text and end text straight capital delta E subscript text int end text end subscript equals 0$
