In thermodynamics,which one of the following is not an intensive property?

One mole of an ideal gas at $25\,^{\circ}C$ expands its volume from $1\,L$ to $4\,L$ at constant temperature. What work (in $J$) is done if the gas expands against a vacuum $(P_{ext} = 0)$?

Which of the following is not a state function of a thermodynamic system?

An adiabatic process is experienced by a/an ...... system.

For the reversible isothermal expansion of $1 \, \text{mol}$ of an ideal gas at $300 \, K$ from a volume of $10 \, dm^3$ to $20 \, dm^3$,the value of $\Delta H$ in $kJ$ is:

In an exothermic reaction,the reactants:
