How much work in $kJmo{l}^{-1}$ unit is done by reversible and isothermal expansion of $1.2$ mole of an ideal gas to $10$ times of its original volume at ${27}^{o}C$ ?

For an ideal gas, the work of reversible expansion under isothermal condition can be calculated by using the expression $W=-nRTln\frac{V_f}{V_i}$. A sample containing 1.0 mol of an ideal gas is expanded isothermally and reversible to ten times of its original volume, in two separate experiments. The expansion is carried out at 300 K and at 600 K respectively. Choose the correct option.
(a) Work done at 600 K is 20 times the work done at 300 K
(b) Work done at 300 K is twice the work done at 600 K
(c) Work done at 600 K is twice the work done at 300 K
(d) $\Delta$U = 0 in both cases

The amount work done by 2 moles of an ideal gas at 298 K in reversible isothermal expansion from 10 litres to 20 litres is.

Calculate the work done for a reversible isothermal expansion of one mole of an ideal gas at ${127}^{\circ }C$ from a volume of $10d{m}^3$ to $20d{m}^3$
