Two different thermodynamic systems are described by the following equations of state: 1T(1) = 3RN(1)2U(1) and 1T(2) = 5RN(2)2U(2) where T(1,2), N(1,2), and U(1,2) 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 thermal contact and attain thermal equilibrium. The ratio U(2)Utot is:
