A closed system of mass 5 kg undergoes a process in which there is work of
magnitude 9 kJ to the system from the surroundings. The elevation of the system
increases by 700 m during the process. The specific internal energy of the system
decreases by 6 kJ/kg and there is no change in kinetic energy of the system. The
acceleration of gravity is constant at 9.6 m/s 2 . Determine the heat transfer, in kJ.
