An ideal gas expands in volume from $1 \times 10^{-3} \ m^3$ to $1 \times 10^{-2} \ m^3$ at $300 \ K$ against a constant pressure of $1 \times 10^5 \ N \ m^{-2}$. The work done is

$A$ gas is allowed to expand against a constant external pressure of $2.5 \ bar$ from an initial volume '$x$' $L$ to a final volume of $4.5 \ L$. If the amount of work done is $5 \ dm^3 \ bar$,what is the value of '$x$' (in $L$)?

The enthalpies of the elements in their standard states are assumed to be
