What is the work done when a gas is compressed from $2.5 \times 10^{-2} \ m^3$ to $1.3 \times 10^{-2} \ m^3$ at a constant external pressure of $4.05 \ bar$ (in $J$)?

Which of the following reactions shows work of compression?

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:

Which of the following are extensive properties?

Out of boiling point $(I)$,entropy $(II)$,$pH$ $(III)$ and $emf$ of a cell $(IV)$,intensive properties are

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 $(R=8.3 \ J \ K^{-1} \ mol^{-1})$.
