5. (20%) There are two chambers filled with air and butane in an insulated cylinderas shown in the figure below. The plate that separates the two chambers is rigidwhich means it does not move. Both chambers remain at the same temperaturedue to the heat transfer through the rigid plate. A piston is used to compress the airfrom the left side. Initially air is at 500 KPa, 200℃ with volume of 0.01 m3 andbutane is at 1500 kPa, 200℃ with the volume of 0.01 m3. Air is compressedreversibly such that the temperature of the gases is raised to 225*C. Determine: (1)final pressure of both gases； (2) heat transferred between the chambers； (3) thework performed on air. All heat losses to the surroundings can be neglected.Assume air and butane to be ideal gases with constant specific heats.
