Problem

\frac{P_1}{P_2}=\frac{n_1T_1}{n_2T_2}

, where

n_1

and

n_2

are the numbers of moles and

T_1

and

T_2

are the respective temperatures. If the two containers are joined, find the ratio of pressure to temperature. (a)

\frac{P_1T_2+P_2T_1}{2T_1T_2}

(b)

\frac{P_1T_1-P_2T_1}{T_1T_2}

(c)

\frac{P_1T_1+P_2T_2}{T_1T_2}

(d) None of these
