Unformatted text preview: constant pressure. 3) (12 points) A Carnot engine operates in such a way that work is performed. The temperature changes from 100K to 200K in the adiabatic compression process and the entropy changes from 300J/K to 600J/K in the isothermal expansion process. a) [6] How much net work is performed during the complete cycle? b) [6] What is the efficiency of the engine? 4) (12 points) n moles of a diatomic ideal gas goes through the cyclic process shown in the figure. The path of the process can be followed by introducing an angle between 0 and 2 such that : P=P + P 1 sin( ) ; V=VV 1 cos( ) a) [6]What is the internal energy U( )? b) [6] What is the net work accomplished each cycle?...
