Question

An insulated container with a capacity of 0.5 m3 is divided by a conductive rigid membrane, into two spaces a and b, each with a capacity of 0.25 m3. space a contains air at 1.4 bar pressure and 290 k, and space b contains air at 4.2 bar and 440k. for air, take x- 0.715 kg k and r-0.287 kj / kg k. calculate:
a.the final equilibrium temperature,
b.the final pressure on each side of the container, and
c.the entropy change of the air in both sides of the container using gibbs equations.
