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

What is the work done in $cal$ during the reversible isothermal expansion of $1 \, mol$ of an ideal gas at $300 \, K$ from $10 \, atm$ to $1 \, atm$?

For a reversible process at $T = 300 \, K$,the volume increases from $V_i = 1 \, L$ to $V_f = 10 \, L$. If the process is isothermal,find the value of $\Delta H$ in $kJ$.

An ideal gas undergoes isothermal expansion at constant pressure. During the process

Prove the relationship between $C_p$ and $C_v$ for an ideal gas.

At $T(K)$, $2 \ mol$ of an ideal gas is allowed to expand reversibly and isothermally from a pressure of $10 \ atm$ to $1 \ atm$. The work done (in $kJ$) is $(R=8.3 \ J \ K^{-1} \ mol^{-1})$.
