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

Work done during isothermal expansion of $1 \, \text{mole}$ of an ideal gas from $10 \, \text{atm}$ to $1 \, \text{atm}$ at $300 \, \text{K}$ is ....... $\text{cal}$ (Gas constant $R = 2 \, \text{cal} \, \text{K}^{-1} \, \text{mol}^{-1}$) (in $.8$)

Which of the following is a set of intensive properties?

Five moles of an ideal gas at $1 \ bar$ and $298 \ K$ is expanded into vacuum to double the volume. The work done is :-

For the reaction $N_{2(g)} + 3H_{2(g)} \to 2NH_{3(g)}$,the relationship between $\Delta H$ and $\Delta U$ is:

What is meant by standard state in the context of the equation $\Delta U = q + w$?
