Two containers of equal volume contain the same gas at pressures P1 and P2 and absolute temperatures T1 and T2 respectively. On joining the vessels, the gas reaches a common pressure P and common temperature T. The ratio P/T is equal to

1. P1T1+P2T2                           

2. P1T1+P2T2T1+T22

3. P1T2+P2T1T1+T22                     

4. P12T1+P22T2

4.    Number of moles in first vessel μ1=P1VRT1 and number of moles in second vessel μ2=P2VRT2        If both vessels are joined together then quantity of gas remains same i.e. μ=μ1+μ2         P2VRT=P1VRT1+P2VRT2         PT=P12T1+P22T2
