\mathrm{Q= \Delta U+W\: ,W= 400\, J}
For Isobaric process,

\\ \mathrm{Q=nC_{p} \Delta T} \\ \mathrm{ \Delta U= nC_{v}\Delta T }

\mathrm{\frac{Q}{\Delta U}= \gamma = 1.4 \quad        
\mathrm{Q= \frac{Q}{1.4}+400}
\mathrm{Q\left ( 1-\frac{1}{1.4} \right )= 400, Q= \frac{400\times 1.4}{0.4}}
\mathrm{Q= 1400 J}
