Which of the following is $NOT$ an intensive property?

In an exothermic reaction,the reactants:

Consider the reversible isothermal expansion of an ideal gas in a closed system at two different temperatures $T_1$ and $T_2$ $(T_1 < T_2)$. The correct graphical depiction of the dependence of work done $(|w|)$ on the final volume $(\ln V)$ is:

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

The work done during the expansion of $1 \ mol$ of an ideal gas into a vacuum is ............ .

Among the following,the state function$(s)$ is(are):
$A$. Internal energy
$B$. Irreversible expansion work
$C$. Reversible expansion work
$D$. Molar enthalpy
