Solution

The correct option is B dU is negative
V = constant. Gas will release heat to surrounding, hence $d Q$ < 0

$d Q = d U + W$

$d Q = d U + 0$

$d U = d Q < 0$

$d U < 0$

The correct option is B dU is negativeV = constant. Gas will release heat to surrounding, hence dQ < 0 dQ=dU+W dQ=dU+0 dU=dQ<0 dU<0

The correct option is B dU is negative
V = constant. Gas will release heat to surrounding, hence $d Q$ < 0

$d Q = d U + W$

$d Q = d U + 0$

$d U = d Q < 0$

$d U < 0$
