If a cylinder containing a gas at high pressure explodes,the gas undergoes

$A$ perfect gas contained in a cylinder is kept in vacuum. If the cylinder suddenly bursts,then the temperature of the gas

$Assertion :$ Reversible systems are difficult to find in the real world.
$Reason :$ Most processes are dissipative in nature.

In a thermodynamic process for free expansion, select the '$WRONG$' statement out of the following options.

Explain the quasi-static process.

$A$ container of volume $1 \ m^3$ is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at $300 \ K$. The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be ..... $K$.
