A gas is taken round the cycle shown in the pressure-volume diagram. On the diagram the cycle is a circle, running clockwise. The pressure goes between $1 \times 10^5\ \text{Pa}$ and $3 \times 10^5\ \text{Pa}$, and the volume between $1 \times 10^{-3}\ \text{m}^3$ and $3 \times 10^{-3}\ \text{m}^3$. The net heat absorbed by the gas in one cycle is closest to
