Solution

The correct option is B if pressure of system > atmospheric pressure.
As we know,
$w = P_{e x} (Δ V)$
if pressure of system > atmospheric pressure
then,
Energy can transfer form system to surroundings as work.

Q. Statement - 1
Two vessels A and B are connected to each other by a stopcock. Vessel A contains a gas at

0^{o} C

and 1 atmosphere pressure and vessel B is evacuated. The two vessels are thermally insulated from the surroundings. If the stopcock is suddenly opened, there will be no change in the internal energy of the gas.

Statement - 2
No transfer of heat energy takes place between the system and the surroundings.

Q. A system generates
