360194 A vessel of volume 3 \(V\) contains a gas at pressure \(4 P_{0}\) and another vessel of volume \(2 V\) contains the same gas at pressure \(1.5 P_{0}\). Both vessels have same temperature. When both vessels are connected by a tube of negligible volume, the equilibrium is pressure \(I P_{0}\), where \(I\) is an integer. Find the value of \(I\).
