## Homework Statement

A and B are two identical containers connected by a tap initially closed. A contains an ideal gas at a pressure P1 and temperature T1. B contains the same gas at a pressure P2 and a temperature T2. The tap is the opened. If the temperatures of the containers A and B remain constant at T1 and T2 respectively, the final pressure of the gas mixture will be:

A.(P1+P2)/2

B.(P1+P2)

C.(P1T1+P2T2)/(T1+T2)

D.(P1T2+P2T1)/(T1+T2)

E.(P1/T1 + P2/T2)(T1+T2)

## Homework Equations

PV=nRT

## The Attempt at a Solution

P1 X 1 = n1 RT1 P2 X 1=n2 RT2

:( thats all i can do
