Correct option is : (1) 350 J
For Isobaric process
\(\mathrm{w}=\mathrm{P} \Delta \mathrm{v}=\mathrm{nR} \Delta \mathrm{T}=100 \mathrm{~J}\)
\(\mathrm{Q}=\Delta \mathrm{u}+\mathrm{W}\)
\(\Delta \mathrm{Q}=\frac{\mathrm{F}}{2} \mathrm{nR} \Delta \mathrm{T}+\mathrm{nR} \Delta \mathrm{T}\)
\(\left(\frac{\mathrm{f}}{2}+1\right) \mathrm{nR} \Delta \mathrm{T}\)
\(\left(\frac{5}{2}+1\right) 100=350 \mathrm{~J}\)
