Solution

The correct option is A $32 cm$
Here,
$P_{1} = (76 + 5) cm Hg$
$P_{2} = (76 + h) cm Hg$
$V_{1} = 4 L$
$V_{2} = 3 L$
Since temperature is constant,
$P_{1} V_{1} = P_{2} V_{2}$
$81 \times 4 = (76 + h) \times 3$
$\Rightarrow h = 32 cm$

He gas is transferred from container A to container B at constant temperature. Find the value of h (Patmosphere=76 cm Hg)

The correct option is A 32 cm Here, P1=(76+5) cm Hg P2=(76+h) cm Hg V1=4 L V2=3 L Since temperature is constant, P1V1=P2V2 81×4=(76+h)×3 ⇒h=32 cm
