A well-insulated, rigid vessel is divided into two compartments by a partition. The volume of each compartment is 0.1 m³. One compartment initially contains 400 moles of gas A at 300K, and the other compartment is initially evacuated. The partition is then removed and the gas is allowed to equilibrate. Gas A is not ideal under these circumstances but can be described well by the following equation of state: P=RT/(Vm-b)-a/(TVm²) with constants a=40 [(J K m³)/mol²] and b=3 x 10⁻⁵ m³/mol You may take the ideal gas heat capacity of gas to be Cv,mideal=3R/2. Calculate the final temperature.
