A fixed volume insulated tank, which was initially empty, was connected by a valve to a distribution line carrying helium gas at a temperature of 125ºC. The valve is opened first and closed when the pressure is the same as the distribution line pressure. What is the final internal energy of helium in the tank? (Internal energy of the warehouse in the final state = Enthalpy of the distribution line). (Cp=5.1926) will be taken.
