A rigid and insulated tank of `3m^(3)` volume is divided into two compartments. One second compartment of volume of `2m^(3)` contains an ideal gas at 0.8314 Mpa and 400K and while the second compartment of volume `1m^(3)` contains the same gas at 8.314 MPa and 500K. If the partition between the two compartments isruptured. the final temperature of the gas is:

A

420K

B

450K

C

480K
