• # question_answer n moles of an ideal gas with constant volume heat capcity ${{C}_{V}}$undergo an isobaric expansion by certain volume. The ratio of the work done in the process, to the heat supplied is: [JEE Main 10-4-2019 Morning] A) $\frac{4nR}{{{C}_{V}}-nR}$        B) $\frac{nR}{{{C}_{V}}-nR}$C) $\frac{nR}{{{C}_{V}}+nR}$        D) $\frac{4nR}{{{C}_{V}}+nR}$

$w=nR\Delta T$           $\Delta H=({{C}_{\text{v}}}+nR)\Delta T$           $\frac{\text{w}}{\Delta H}=\frac{nR}{{{C}_{\text{v}}}+nR}$
