Problem

The ratio of pressure of the same gas in two containers is

\frac{n_1 T_1}{n_2 T_2}

where

n_1

and

n_2

are the number of moles and

T_1

and

T_2

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

\frac{P_1 T_2 + P_2 T_1}{2 T_1 T_2}

(b)

\frac{P_1 T_1 - P_2 T_1}{T_1 T_2}

(c)

\frac{P_1 T_1 + P_2 T_2}{T_1 T_2}

(d) None of these
