138905 Two cylinders $A$ and $B$ of equal capacity are connected to each other via a stopcock. A contains an ideal gas at standard temperature $\left(T_{1}\right)$ and pressure $B$ is empty. Then the entire system is thermally insulated. The stopcock is suddenly opened. After the gas reaches equilibrium the temperature $\left(T_{2}\right)$ of the gas measured. Which of the following is correct?
