During free expansion of an ideal gas no work is done and also no heat is supplied from outside. Therefore from first law of thermodynamics no change in internal energy. Q=W=0and Δ U=0

Q. For the free expansion of an ideal gas under adiabatic conditions, which of the following is true?

$Q = W = 0 an d Δ U = 0$

$Q \neq = 0$ , $W = 0$ and $Δ U = W$

$Q = 0$ , $W \neq = 0$ and $Δ U = W$

$Q \neq = 0$ , $W \neq = 0$ and $Δ U = 0$

During free expansion of an ideal gas no work is done and also no heat is supplied from outside. Therefore from first law of thermodynamics no change in internal energy.
$Q = W = 0 an d Δ U = 0$
