In an adrabatic process wherein pressure is increased by $\frac{2}{3} \%$. If $\frac{C_{p}}{C_{V}}=\frac{3}{2}$, then the volume decreases by about

An ideal gas is taken through a cyclic thermodynamical process through four steps. The amounts of heat involved in these steps are $Q_{1}=5960 \,J , Q_{2}=-5585 \,J , Q_{3}=-2980\, J$ $Q_{4}=3645\, J$; respectively. The corresponding works involved are $W_{1}=2200\, J , W_{2}=-825\, J, W_{3}=-1100 \,J$ and $W_{4}$ respectively. The value of $W_{4}$ is
