Answer to Question #121605 in Electrical Engineering for Alwin

Question #121605
Two systems have the following equations of state, where RR is the gas constant per mole. The mole numbers are N1​ = 3 and N2​ = 5. The initial temperatures are T1​ = 175 K and T2​ = 400 K. What is the temperature once equilibrium is reached (in Kelvin)?
1/t1=3/2(R*N1/U1)
1/t2=5/2(R*N2/U2)​

The temperature once equilibrium is reached can be found from the following ideal gas law. Initially, we have



In the equilibrium, we have



If pressure and volume did not change, we have
