Two different thermodynamic systems are de scribed by the following equations of state: 3RN) 2U(1) 5RN) 2U(2) 1 1 and TO T2) where T(1,2) .NU,2) and UL2) are respectively, the temperatures, the mole numbers and the internal energies of the two systems, and R is the gas constant. Let Utot denote the total energy when these two systems are put in contact and attain thermal equilibrium.. The ratio is U1) Utot 5N2) 3N1) (bN1) +5N?) a3N)+5N?) (c)) + N N2) N)+ N2) N) (d)
