A hot fluid, stored in a rectangular tank, is cooled while being stirred by a paddle wheel. During this process, the fiuid loses 5400J of heat and the paddle wheel does 17kJ of work on the fluid. The initial internal energy is given as 460kJ. Determine the final internal energy. Given: U=Q+W;H=U+PV.R=8.314J/mol.K Q=RTlnV1V2=RTlnP1P2
