(E) Rotating shaft. (1g). (2p) The least number of independent intensive properties needed to specify a state of a simple compressible system is (A) 1 B) 2 (0) 3 D 4 (E) 5 (1h). (2p) For a closed system, work is the only possible way to transfer energy between two specified states if the process is (A) Isobaric. (B) Isochoric. (C) Isothermal (D) Adiabatic. (E) None of the above. 2. (10 points) A Toyota Camry of mass 1,150 kg turns from Cheat Road to Route 68, thereby accelerating from 35 MPH in the city till 70 MPH on the freeway in 5 seconds. You can neglect the weight of the driver, friction and aerodynamic drag. (2a) (6p) Please calculate the work done by the engine for this acceleration, in kJ. (2b) (4p) Please calculate the average power delivered by an engine under these conditions, in kW.
