143173 The volumes of containers $A$ and $B$, connected by a tube and a closed valve, are $V$ and $4 V$ respectively. Both the containers $A$ and $B$ have the same ideal gas at pressures (temperatures) $5.0 \times 10^{5} \mathrm{~Pa}(300 \mathrm{~K})$ and $1.0 \times 10^{5} \mathrm{~Pa}(400 \mathrm{~K})$, respectively. The valve is opened to allow the pressure to equalize, but the temperature of each container is kept constant at its initial value. Find the common pressure in the containers
