Heat And Thermodynamics

Two gases occupy two containers \(A\) and \(B\). The gas in \(A\) of volume \(0.20 \mathrm{~m}^3\), exerts a pressure of \(1.40 \mathrm{~MPa}\) and that in \(B\), of volume \(0.30 \mathrm{~m}^3\) exerts a pressure of \(0.7 \mathrm{~MPa}\). The two containers and united by a tube of negligible volume and the gases are allowed to exchange. Then, if the temperature remains constants. the final pressure in the container will be (in MPa).
