Two identical containers joined by a small narrow pipe initially contain the same gas at pressure p₀ and absolute temperature T₀. One container is now maintained at the same temperature while the other is heated to 2T₀. The common pressure of the gases will be

• A

  $\frac{3}{2}{\mathrm{p}}_0$

• B

  $\frac{4}{3}{\mathrm{p}}_0$

• C

  $\frac{5}{3}{\mathrm{p}}_0$

• D

  2p₀
