1.

Two thermally insulated vessel 1 and 2 are filled with air at temperature `(T_1T_2), volume (V_1V_2)` and pressure `(P_1P_2)` respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will beA. `T_(1) + T_(2)`B. `T_(1)T_(2) (P_(1)V_(1) + P_(2)V_(2)) // (P_(1)V_(1)T_(1) + P_(2)V_(2)T_(2))`C. `T_(1)T_(2) (P_(1)V_(1) + P_(2)V_(2)) // (P_(1)V_(1)T_(2) + P_(2)V_(2)T_(1))`D. `(T_(1) + T_(2)) // 2`
