15. Consider a cylinder of fixed volume comprising two compartments that are separated by a freely movable, adiabatic piston. In each compartment is a 2.00 mol sample of perfect gas with constant volume heat capacity of 20 JK-1 mol-¹. The temperature of the sample in one of the compartments is held by a thermostat at 300 K. Initially the temperatures of the samples are equal as well as the volumes at 2.00 L. When energy is supplied as heat to the compartment with no thermostat the gas expands reversibly, pushing the piston and compressing the opposite chamber to 1.00 L. Calculate a) the final pressure of the of the gas in the chamber with no thermostat. [2] b) the final temperature of the gas in the chamber with no thermostat. [2] c) the change in entropy of the gas in the chamber with no thermostat. [2] d) the change in entropy of the gas in the chamber with thermostat. [2] the change in interna energy of the gas in the chamber with no thermostat. e) [2] g) the change in internal energy of the gas in the chamber with thermostat. [2] Calculate AA using AS and AU you determined above for each chamber and rationalize where not possible. [6]
