Physics - Heat & Thermo Question with Solution | TestHub

Two moles of a monoatomic gas go through a cycle shown on a $P$-$T$ graph: $1\to 2$ and $3\to 4$ are lines through the origin, and $2\to 3$ and $4\to 1$ are isobaric. The temperatures are $T_1=300$ K, $T_2=600$ K, $T_3=1800$ K and $T_4=900$ K. Find the work done per cycle in kJ (one decimal, $R=8.314$ J $mo{l}^{-1}$$K^{-1}$).
