Question

Two thermally insulated vessels 1 and 2 are filled with air at temperatures $\left( {{T_1},{T_2}} \right)$ volume $\left( {{V_1},{V_2}} \right)$ and pressure $\left( {{P_1},{P_2}} \right)$ respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will be

Accepted Answer

$\frac{{{T_1}{T_2}\left( {{P_1}{V_1} + {P_2}{V_2}} \right)}}{{{P_1}{V_1}{T_2} + {P_2}{V_2}{T_1}}}$

Answer

${T_1} + {T_2}$

Answer

$\left( {{T_1} + {T_2}} \right)/2$

Answer

$\frac{{{T_1}{T_2}\left( {{P_1}{V_1} + {P_2}{V_2}} \right)}}{{{P_1}{V_1}{T_1} + {P_2}{V_2}{T_2}}}$
