Which of the following is an example of an intensive property of the system?

During the reversible isothermal expansion of an ideal gas,the change in internal energy is......

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 $1 \, atm$?

The intensive property among these quantities is

For the reaction of nitrogen with hydrogen to form ammonia,$\Delta H^o = -92.2 \ kJ/mol$. If the reaction is carried out at a constant pressure of $20.0 \ atm$ and a volume change of $-1.16 \ L$,calculate the change in internal energy $(\Delta U)$ in $kJ$.

When a solvent is added to a solution,the heat of the solution $...$.
