Two containers (a and b) are in thermal contact with an environment at temperature t = 280 k. the two containers are connected by a tube that contains an ideal turbine (a mechanical device) and a valve. initially, the valve is closed. container a (volume va = 2 m3) is filled with n = 1.2 moles of an ideal monatomic gas, and container b (volume vb = 3.5 m3) is empty (vacuum). when the valve is opened, gas flows between a and b, and the turbine is used to generate electricity. what is the maximum amount of work than can be done on the turbine as the gas reaches equilibrium?
