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)

    first thing there is a mistake , it's in N^2 in equation 2. now it is very easy question, always remember extensive property is additive and examples of extensive quantities are entropy, volume, no of moles, density..this additive property is very important..
